There are many vintage Seiko divers popular with collectors, and the legendary 7S26 – like this bright orange 2003 Seiko SKX011J automatic diver here, with its inner/outer boxes, instructions manual, and warranty paperwork – is one of these. 
 
With good reason, Seiko was able to build a tremendous cult following around the SKX - of significant note, Seiko unwisely discontinued these legendary divers in 2019, immediately driving up demand due in part to its less than ideal successor.
 
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.
 
There remains a fair bit of debate among Seiko aficionados, with the argument on balance this variant - the "Made in Japan" one - is superior in quality to SKX examples made elsewhere, for example in Malaysia.
 
Regardless, during its heyday, the SKX was popular with various armed forces for this same reason - its extreme durability - despite the widely held (false) assumption that military personnel only wear military watches issued to them
 
Seiko’s 7S26 was a logical step in its mechanical movement line, which debuted in 1996 to replace the 7002 in Seiko’s popular dive watch line, and incorporates quickset day and date displays, and automatic bi-directional winding via Seiko’s patented Magic Lever system.
 
The orange dial variant was first released in the mid-1990s as the SKX011K, and was likely targeted at the South East Asian market - Seiko discontinued, for unclear reasons, the SKX011K in favor of its successor, the sought-after Made in Japan SKX011J variant here.
 
This Seiko diver comes on a Seiko jubilee bracelet, and with nylon strap, rugged travel case, and springbar tool.
