One of Seiko’s most striking designs from their 70-meter diver range of watches that they produced starting in the late 1960s. This example is a one-owner watch that has never been serviced; it is entirely original down to the caseback seal and crystal.

• 6106C movement is in good physical working condition. It is unserviced, and should be serviced before wearing. Movement hacks, time sets, quicksets, automatic winding winds, day & date roll over at midnight. Daywheel is slightly misaligned but this can be corrected during a service.

• Case is in good original condition with no corrosion or major damage. It shows wear commensurate with a single owner who wore the watch for a period but never abused it. Sharp case lines, intact brushing. Crystal has a haze of small marks.

• Lume is slightly darkened and dirty on the dial and hands, main sweep hand is slightly faded.

• Head-only

• watch is unserviced and is not warrantied
