For today's watch I chose something big and square from one of the more popular mystery brands.
This watch is an analogue quartz watch by the Metro brand. It is called the Washington, and follows one of the naming trends the Metro brand uses which is American cities. This does make it more difficult for a web search as the city of Washington has a metro (subway) which swamps the results. The watch is also quoted as being a special edition, but as you don't see too many of any if the models, I don't know how much it really means. The brand itself is a bit of a mystery, with very little written about it, but the watches are always popular on the Japanese auctions.
The Washington Special Edition is a little more complicated than others from the brand I've blogged. It has a 3 hand dial analogue dial, with 2 smaller dials (at 3 an 9) for the day and date. At the 6 o'clock position, there is also a moon phase dial which is not such a common watch feature. The dial is square and quite large (3x3cm), and sits in a larger rectangular case (3.5x4.5cm) with sloped sides. The back has minimal info, just showing the brand and model names.
I haven't yet confirmed the date of the watch, but my best guess is that the brand was around in the late 90s or 2000s.
