Seiko The Blackdiamond Collection – Multi-Time Quartz

A charmingly eccentric piece from Seiko’s elusive Blackdiamond Collection, this watch blends classical styling with unconventional complications — a hallmark of this collectible and often experimental series.

Housed in a polished gold-tone round case with Roman numeral indices, the dial features a multi-textured center and three timekeeping displays:

• The central hands show your main local time.
• A striking blue retrograde-style hand at the 11 o'clock position indicates a second time zone.
• A framed date window at 3 o’clock completes the layout.

This watch is powered by a precise Seiko quartz movement, operated via two additional pushers on the side of the case that independently adjust the auxiliary hands.

Paired with a classic brown leather strap, this watch is both a conversation piece and a practical travel companion. A must-have for Seiko collectors, especially those drawn to unusual, JDM-exclusive complications.
