here is something not so often to find:) **Seikosha Chronograph, WW2 with military marks.** The Watch came out of the workshop of the **master Hattori Tokei (Seiko ofc :)) who was the supplier of the Japanese Imperial Army** at the time and I presume that it is also the first series of seiko pocket chronographs. The inscription "Seikosha" is located below the upper sub. The size of the case is 51.5mm. According to the net info, the case, dial and shape of the watch were created by "copying" the Swedish military Minerve from the 30s. Chrono rotates fine, resets, and the upper sub is labeled up to 30min. Lume still exists on hour markers and chrono seconds. **The backcase carries military marks,** From this section we can determine that the watch is military origin, the number of case, belonged to a member of the air forces (this is the mark in the circle . In the upper row of the symbol, it is marked that it is chronograph, has lume, the clock is a pilot type, "reserve" 24h. and probably something else Here's a picture from the internet where most of the same symbols are: http://i392.photobucket.com/albums/pp7/Seiji5508/2-17-2016%2012-18-23%20PM\_1.jpg It works nice, chrono is also reseting to 0, **Full service is made 09.2023**. I think it is excellent part of history and I hope somebody will continue to enjoy in it as I am.
