Even among vintage Seiko watches, square watches are rare, and it's rare to find one in good condition that has survived for over 50 years.
This is one of my treasured collections, built over the years. I'm particularly drawn to antique Japanese Square Aces, and have a collection of several. This is one of them.
Look at this square case with its sharp edges, and the beautiful, pristine dial makes it hard to believe it was made half a century ago. I think it's an extremely collectible piece.
A Seiko manual-winding Unique from the 1950s. This is a rare rectangular watch with a genuine Seiko case.
The crown also bears the original S mark.
This is a completely original vintage watch.
The SEIKO UNIQUE name font is also blocky, a design not used on any Unique models from the same era, and seems to be inspired by the square case, making this a truly unique and rare model.
In preparation for listing, this watch was overhauled at a watch shop in December 2024. It comes with a new black strap. No invoice will be included. Daily accuracy: ±30 seconds.
The photos clearly show this watch features a rare, original Seiko square 20-micron gold-plated case with simple bar indexes! A hand-wound watch from this era, with a center second hand, is a great feature.
The dial is a beautiful silver dial, and is in such good condition that it's hard to believe it's a square watch.
The reference number is 10195, with a lug width of 19mm.
The square shape of the Seiko Vintage watch, combined with its Art Deco design, makes it a truly stunning hand-wound watch.
The case diameter is approximately 43mm long and 36mm wide. This vintage size looks great on both men and women.
It seems that Ginza CTI, a long-established antique watch retailer, has also produced similarly good quality unique square watches in the past. Extremely rare.
A new black strap will be included.
