Seiko SKX173 from 2004 (NOS | Movement Singapore)

Seiko SKX173 – New Old Stock from 2004

There are few watches that capture the spirit of Seiko’s tool-watch legacy quite like the SKX173. Often seen as a transitional reference between the 7002 and the later SKX007, the SKX173 holds a unique place in Seiko’s dive watch history—marrying the robust, utilitarian design of the earlier 7002 with the upgraded 7S26 automatic movement that would go on to define a generation of divers.

This particular example is a true time capsule: a New Old Stock piece from 2004 that has never been worn, complete with its original box and papers. Both the dial and caseback are marked “Mov’t Singapore,” a nod to the watch’s Southeast Asian production lineage, and the movement rotor is appropriately signed “Singapore.” These markings were typical of early 2000s Seiko production and add a layer of regional character to an already rare reference.

What makes the SKX173 stand out—especially to collectors—is its dial design. Unlike the rounded indices of its more commonly seen sibling, the SKX007, the 173 features bold rectangular hour markers, a clear aesthetic continuation from the 7002, lending it a sharper, more functional look. The result is a watch that feels both vintage and modern, utilitarian yet charismatic.

The watch comes mounted on a brand-new aftermarket bracelet, ready to wear or collect. With its untouched condition and full set, this SKX173 is a rare opportunity to acquire a nearly two-decade-old diver that looks like it just left the factory.

For privacy, the serial number has been discreetly covered, providing complete ownership discretion.
