Seiko Prospex SPB105 Dive Watch

By Andrew Gatto

On June 16th, Seiko USA (@seikowatchusa) posted a single photo of a new Prospex 200m diver reference on their Instagram account. The new Prospex SPB105 is a green dial variant of the 2018 modern reinterpretation of the famous Seiko 6159 dive watch originally from 1968. As many Seiko fans are aware, they released two versions of the 6159 reissue at Baselworld 2018; a faithful limited edition reissue as well as a non-limited modern reinterpretation that was more affordable and available in several dial colors and strap options.


 
 

This newly teased SPB105 has the same case and bracelet design as the modern reinterpretations; however, it is now being offered with a beautiful green dial and gold-colored hands. The rotating bezel is black, which some are saying clashes with the stainless steel case, green dial, and gold hands. But without seeing hands-on photos of this watch it is difficult to determine with certainty. At this time, it appears the new SPB105 is only offered on a stainless steel bracelet with no factory rubber strap option.

This isn’t Seiko’s first green dial Prospex dive watch; the 2018 limited edition “Marine Master 300” SLA019 featured a similar green dial and even a green ceramic rotating bezel.

Seiko has given conflicting release dates of summer 2019 and fall 2019, so I guess it’ll be a pleasant surprise when it is actually available for purchase. The MSRP is slated to be $1,050 USD.
