The IWC Portugieser 3716 takes the looks from the classic 3714, but upgrades these with a newer movement, a see-through back, and other small tweaks. The first 3716’s showed up in the ‘150th Anniversary’ collection of 2018, trickling down to the regular collection in late 2019.Reference IW3716-15 has a Stainless Steel case and a Green dial. This was added to the collection in 2020.
