Up for sale is what I think is a pre-WWII era Seiko watch, with a triple-sunk porcelain dial, arabic numerals, and blued steel hands.  Note that as is common with these early models, the movement is stamped "Seikosha."  It comes on what I think is its original leather strap, of a style that I think is sometimes referred to as a "bund" strap, which I've seen mostly on pre-WWII and WWI-era watches from Japan.  It has some interesting patterning on the metal hardware that you can see on the photos.  The watch has what are called "wire lugs," I believe making it what is commonly referred to as a "trench watch," so called because they were used in the trenches during WWI as the first practically-useful wristwatches (as opposed to the more prevalent pocket watches of the time).  The watch came to me in a large lot of watches I bought directly from Japan, all of which were from this era.  The watch isn't marked as military-issue anywhere, though I have purchased these types of models with these bands with militariana at times, and I do think they were often used in WWII.  Of particular interest is that this watch looks an awful lot like the model I have seen described on multiple watch blogs/posts as being the "first" watch to ever bear the name Seiko on it.  See one such example here.

The watch winds, sets, and runs.  During the 17 hours I observed it gained a single second, which is astonishingly good, though I have no idea when (if ever) it was last serviced.  Cosmetically, the dial has some noticeable damage in the top left quadrant, but it is otherwise in very nice shape, and the strap is in surprisingly decent condition.  The case shows some wear to the chrome, but given it's age it's really quite nice.  The case also says "gold coin watch case" on the inside, which I don't find totally surprising... the earliest Seikos sometimes used Swiss movements, or their own movements in Swiss cases.

These are pretty darn hard to find in the U.S., and even non-functioning are pretty valuable, I think.  I'm listing several other similar watches, and am of course happy to combine them into one box for shipping if you win multiple lots (with the caveat below about international shipping).  Happy bidding!

I'm an amateur collector of vintage Japanese watches, mostly Seiko and Citizen.  As such, I won't accept returns unless the watch arrives in different condition than as described.  Please examine all photos as they are part of my description.  This will only ship internationally via ebay's "global shipping program," which is the (expensive) quote you should automatically see in the listing if you aren't in the U.S.  In my first real attempt at using this, I received messages from folks in Spain, England, and France all telling me that it wouldn't let them bid, so I apologize if it does so for you - there's nothing I can do to correct it :(.  If you have a feedback score of less than 10, please contact me prior to bidding or I may cancel your bid.  I am happy to combine shipping costs as long as whatever I'm selling will fit safely in a flat rate small USPS box, but the Global Shipping Program won't let me do this unless you agree to cancel your auction wins and re-do the sale as a single Buy-it-Now option, so be warned of that eventuality if you are an international bidder.  I generally don't consider a buy-it-now option.  Thanks and happy bidding!
