Rolex Submariner Overview
The Rolex Submariner is one of the world’s most famous dive watches, known for its durability, precision, and iconic design. The lineup includes both No-Date models like the 124060 and Date models like the 126610LN, 126610LV, and earlier references such as 114060, 116610LN/LV, and 16610.
All Submariners use the screw-down Triplock crown, which gives the watch exceptional water resistance up to 300 meters. They also run on COSC-certified movements—Caliber 3230 for No-Date and 3235 for Date models—meeting Rolex’s strict Superlative Chronometer standards.
Knowing these features helps you understand how to set a Rolex Submariner correctly without risking damage.
What You Need to Know Before Setting a Rolex Submariner
Before you begin, you must understand how the Triplock crown works, the watch’s hacking seconds function, how the AM/PM cycle affects the date, and how Rolex movements respond to crown adjustments. These details are important because every step affects accuracy, waterproofing, and mechanical health.
Submariner crowns have three working positions, not counting the screwed-down position. The watch also stops the second hand when the crown is fully pulled out, allowing precise synchronization.
Understanding these basics will help you master how to set a Rolex Submariner without mistakes.
How to Change Time on a Rolex Submariner (No-Date Models)
Setting the time on a No-Date Submariner is simpler, but you still must follow each step carefully. These models include the 124060 and older references, like 114060.
Step 1 — Unscrew the Crown
Turn the crown counterclockwise until the threads fully release and the crown pops outward. Make sure it spins freely—if you feel resistance, stop and adjust your grip.Step 2 — Pull the Crown to the Final Click (Time-Setting Position)
Gently pull the crown out until you feel the second click, which activates hacking seconds. Pull straight outward to avoid bending the stem.Step 3 — Rotate the Hands Forward to the Correct Time
Turn the crown forward only until the hour and minute hands reach the exact time you want. Avoid rotating backward, as it can strain the movement.Step 4 — Use Hacking Seconds to Sync to an Exact Time Signal
Wait for your reference clock to reach the top of the minute, then push the crown slightly inward to restart the seconds hand. Release at exactly “00” to achieve perfect synchronization.Step 5 — Push the Crown Back In and Screw It Down Fully
Press the crown all the way in, then turn it clockwise while pushing to engage the threads. Screw it down firmly until it is fully sealed to maintain water resistance.
How to Change Time on a Rolex Submariner Date
Setting a Submariner Date—such as the 126610LN, 126610LV, 116610, or 16610—requires extra care because of the date mechanism. The date wheel must never be stressed, especially during the “danger hours.”
Step 1 — Unscrew the Crown
Turn the crown counterclockwise until the threads release and the crown springs outward into the winding position. Do not pull yet—confirm the crown rotates freely with no resistance.Step 2 — Pull the Crown to the First Click (Date-Setting Position)
Gently pull the crown out one click; this engages the quickset date mechanism. Pull straight outward to avoid twisting or stressing the stem.Step 3 — Set the Date by Rotating the Crown Forward
Turn the crown forward only until the date changes to the correct number. If the date is far off, rotate slowly and do not rush to avoid misalignment of the date wheel.Step 4 — Pull the Crown to the Second Click (Time-Setting Position)
Pull the crown out one more click to reach the time-setting position; the seconds hand will stop (hacking). Confirm you are fully in the second click—partial engagement can cause the hands not to move.Step 5 — Advance the Hands Forward Until the Date Flips to Determine AM/PM
Turn the crown forward until the date jumps; this indicates midnight. Continue past midnight to set the hour accurately on the correct AM/PM cycle.Step 6 — Rotate the Hands Forward to Your Target Time
Continue turning the crown forward only until the hands reach the exact time you want. Avoid rotating backward, as Rolex specifically advises against reversing the hands.Step 7 — Use Hacking Seconds to Sync Precisely
Wait for an external time source (atomic clock or time app) to reach the top of the minute. Push the crown inward slightly to restart the seconds hand exactly at “00.”Step 8 — Push the Crown In and Screw It Down Fully
Press the crown all the way in and begin rotating clockwise until the threads catch. Screw it down firmly until fully sealed to maintain full water resistance.
How to Change the Date on a Rolex Submariner Date
Only Submariner Date models have this feature, and it must be handled gently. Note that the date-change mechanism is sensitive between 8 PM and 3 AM, known as the danger window.
Step 1 — Unscrew the Crown
Turn the crown counterclockwise until the threads release and the crown pops into the winding position. Ensure it spins freely—this confirms the crown is fully disengaged from the case tube.Step 2 — Pull the Crown to the First Click (Quickset Date Position)
Gently pull the crown outward one click until you feel a defined stop. This activates the date-setting mechanism without moving the hands.Step 3 — Rotate the Crown Forward to Advance the Date
Turn the crown forward only to increment the date one day at a time. Rotate slowly and steadily to avoid skipping or partially engaging the date wheel.Step 4 — Continue Advancing the Date Until You Reach the Correct Number
Keep turning forward until the displayed date matches the correct calendar day. If you pass your intended date, do not turn backward—cycle forward through the remaining days.Step 5 — Push the Crown Back In Fully
Press the crown inward until it clicks back into the neutral (winding) position. Make sure it’s fully seated before beginning to screw it down.Step 6 — Screw the Crown Down Tight to Seal the Case
While pushing in, turn the crown clockwise to re-engage the threads. Tighten until snug to ensure the Submariner remains fully water-resistant.
How to Recognize AM/PM on a Rolex Submariner Date
To determine AM or PM, slowly rotate the hands past 12 o’clock.
If the date changes, you have reached midnight, not noon.
This simple test helps you set alarms, travel times, and other daily functions correctly while setting your Rolex Submariner without confusion.
How to Set a Rolex Submariner After It Stopped
If your Submariner stopped because it was unworn, follow this order:
Unscrew the crown
Wind 30–40 turns for Caliber 3230/3235
Set the time (and date if needed)
Confirm AM/PM
Screw down the Triplock crown
Common Mistakes When Setting a Rolex Submariner
These errors can damage your Submariner or lead to inaccurate timekeeping. Avoid each one to protect your watch.
1. Adjusting the Date Between 8 PM and 3 AM (Submariner Date)
The gears engage during these hours, so forcing the date can break the mechanism. Never adjust the date during this window, even if the watch appears to be functioning normally.
2. Forgetting to Screw Down the Triplock Crown
An unscrewed crown destroys water resistance instantly and can let moisture inside. Water damage is one of the most serious issues for a dive watch. Always remember to tighten the crown fully after any adjustment to maintain its 300m rating.
3. Turning the Hands Backward on Caliber 3235/3135
Moving the hands backward stresses the movement and the calendar system. Rolex movements are designed for forward motion for mechanical safety. Always rotate the hands forward when setting a Rolex Submariner to avoid internal strain.
4. Setting the Time Before Confirming AM/PM
Incorrect AM/PM alignment causes the date to change at noon instead of midnight. This creates long-term confusion and requires resetting the watch again. Do not forget to check the cycle first by advancing past 12 to see if the date switches.
5. Using Excessive Force on the Crown Threads
Forcing the crown can damage the Triplock threads, making it impossible to seal the watch properly. This compromises water resistance and may require expensive crown replacement. Make sure to tighten gently until resistance is felt and never force the crown.
6. Pulling the Crown Out While Underwater or Wet
Opening the crown when it’s wet allows moisture to enter immediately, even with Rolex gaskets. This can permanently damage the movement or cause condensation under the crystal. Ensure your Submariner is dry before adjusting the crown.
7. Setting the Time or Date With Low Power Reserve
If the watch is almost out of power, the movement may not respond smoothly during adjustments. This can cause the hands to skip or the date to misalign. Wind the watch 30–40 full turns before setting anything to keep the mechanism stable and accurate.
8. Pulling the Crown Out Too Quickly
Pulling the crown out too fast may cause you to skip the intended position, leading you to adjust the date when you meant to set the time—or the opposite. This mistake is especially common for new Rolex owners. Slowly pull the crown and feel each click to avoid damaging the setting mechanism or stressing the gears.
How Often Should You Adjust the Time and Date?
You must adjust the date only when the watch stops, when a month has fewer than 31 days, or after changing time zones.
Rolex Submariners have a 70-hour power reserve on Caliber 3230/3235. If you do not wear it regularly, it may stop and require resetting.
Mechanical watches may drift 1–2 seconds per day, even under COSC standards. This means you may need to reset your Submariner weekly, unless worn daily, using the steps taught in how to set a Rolex Submariner.
Useful Tips for Setting a Rolex Submariner
Setting a Rolex Submariner becomes much easier when you follow a few simple habits that protect the movement and improve accuracy. These tips will help you avoid common mistakes and keep your watch performing at its best.
Let the Watch Warm Up Before Setting- If your Submariner was stored in a cold environment, let it sit on your wrist for 10–15 minutes first. A stable temperature helps the lubricants flow properly and ensures smoother crown operation.
Avoid Setting the Watch While It’s on Your Wrist – Remove the watch before adjusting anything. This prevents sideways stress on the stem, which can bend or loosen it over time.
Keep the Crown Area Dust-Free Before Opening – Wipe the crown and surrounding case area with a clean microfiber cloth. Dust or fine particles can get into the tube when the crown is unscrewed.
Always Wind the Watch Slowly and Smoothly – When winding, use calm, even turns—never fast spins. Rapid winding can cause unnecessary friction on the barrel.
If You Overshoot a Time Setting, Keep Rotating Forward – Instead of reversing direction to correct a few minutes, complete another full 12-hour rotation forward. This avoids unnecessary resistance in the hands and keeps the movement stress-free.
After Setting, Do a Final Accuracy Check in 10 Minutes – Let the watch run for a few minutes, then verify the time again. If the second hand didn’t start exactly when you pushed the crown in, this gives you a chance to fine-tune.
Store the Watch Crown-Up to Slightly Improve Accuracy – When not wearing your Submariner overnight, place it in a crown-up position. This position helps compensate for minor daily gains or losses, depending on your specific movement’s behavior.
If Your Watch Has Recently Been Magnetized, Set Time After Demagnetization – A magnetized movement may run fast. Use a demagnetizer first, then set the time—it prevents having to reset repeatedly.
Use Low Light to Check Lume Alignment for Precise Setting – When setting the minute hand exactly at a marker, dim the room slightly. Rolex lume glows and helps you align the hands perfectly.
Avoid Setting the Watch Right After Intense Activity – If the watch was exposed to heavy vibrations (sports, running, tools), let it rest for a few minutes first. This ensures internal components settle before you manipulate the crown.

With the right technique, handling your Submariner becomes simple and stress-free, giving you complete confidence every time you adjust your watch.
FAQ About Setting a Rolex Submariner
Does the Submariner No-Date set differently from the Submariner Date?
Yes. The No-Date Submariner only requires time setting, while the Submariner Date includes a date wheel and a quickset position. This makes the Date version slightly more complex because you must avoid the 8 PM–3 AM danger window.
Why doesn’t my Submariner date change at midnight?
If the date changes at noon instead of midnight, the watch was set in the wrong AM/PM cycle. You must rotate the hands 12 hours forward and reset the time. This is a common mistake when learning how to set a Rolex Submariner Date models.
Do I need to wind my Submariner before setting the time?
If the watch has stopped, yes. You must wind 30–40 turns to activate the movement before setting the time or date. This keeps the mechanism stable when setting a Rolex Submariner after it has stopped.
Can I set the time underwater?
No. Opening the crown underwater allows water to enter immediately, even with Rolex gaskets. Always perform adjustments in a dry environment to protect your Submariner.
