The Seiko Prospex Trans Ocean was introduced in 2016. It features a stainless steel case of 45mm, which is paired with a matching integrated bracelet. This watch is motivated by Seiko’s 6R15 movement. It was among the first Seiko models to have both a sapphire crystal and the Dia-Shield coating on the case & bracelet.Reference SBDC047 is similar but with a blue dial.
