There are many vintage Seiko divers popular with collectors, and the legendary 7S26 – like the freshly serviced and all original late 2001 example here – is one of these. With good reason, the SKX007 continues to have a tremendous cult following, despite Seiko's odd decision to discountinue these legendary divers in 2018.
The design of this 7S26 is classic and simple, with immediate evidence of those that came before it, namely the instantly recognizable Seiko 7002 automatic, 7548 quartz, and even the famous 6309 diver. Its automatic movement is tough and reliable – during its heyday, it was also popular with various armed forces for this same reason, despite the widely held (false) assumption that military personnel only wear military watches issued to them.
Seiko’s 7S26 is a logical step in its mechanical movement line, which debuted in 1996 to replace the 7002 in Seiko’s popular dive watch line. This 7S26 incorporates quickset day and date displays, and automatic bi-directional winding via Seiko’s patented Magic Lever system. The 7S26 automatic movement is a very reliable workhorse – with a power reserve of approximately 40 hours – and it runs at 21,600 beats per hour.
This Seiko diver comes with a rubber dive strap, NATO strap, Pelican travel case, and springbar tool. Of important note, this SKX also comes with an original Seiko 7S26 instruction manual.
