Description

You are bidding on a FANTASTIC set of TWO WW2 Japanese Army and Navy Seikosha Phonotelemeter (Acoustic Distant) Stopwatches!  These were intended for use with Artillery Pieces, as well as Torpedo Boats and Submarines!

  

 This stopwatch was used to measure time intervals with the difference in velocity between light (300,000 km/sec) and sound (300 m/sec).  Most commonly used for artillery range finding, the bearer would measure the time difference between the “flash” and the “bang” produced by an artillery discharge.  This calculation was then used to accurately calculate the target’s distance.  These were used for long-range targeting as well as on board torpedo boats and submarines to measure torpedo running time. 

  

These Seikosha Phonotelemeters are in AMAZING condition!  The manufacture name is clearly marked on the faces, and were manufactured between 1939 and 1945.  “Phonotelemeter” is printed in Latin characters on the porcelain dial (which is normal for this type of watch), and all writing is clearly legible.  Some very fine scratches on the rear of the casings due to the age. 

The watch represented in the wood box is 100% COMPLETE, however the balance staff needes to be replaced in order for it to function correctly.

The one represented outside of the wood box is also 100% COMPLETE, apart from the crystal, which is currently missing.  There is no damage to any of the internal parts, and both the balance staff and main spring are 100% INTACT!  It was functioning 100% until 2 weeks, ago, when it stops, and now does not want to run.  I suspect it just needs a cleaning, but I will leave that to the winning bidder.

At present, both are not functioning, so I am selling them as-is, for display, for parts, or for repair.  Like most Japanese items, these are VERY RARE items, perfect for any collection, or display!

 

Please email me if you need additional photos or information.

——————- TERMS OF SALE —————– 

Most of my items are vintage, and as such are AS-IS, so you must therefore expect a degree of wear due to age and/or usage. I will describe each auction to the best of my knowledge and take as many photos necessary to ensure you are pleased upon receiving your item. All sales are final, so please make sure your questions are answered to your satisfaction before you purchase. 

 

——————- ABOUT ME —————– 

Although my passion is the Me109, I do offer many other German Aircraft (Fw190, Me262, etc.), as well as USAF and Japanese items. Occasionally I do offer many non-vintage items such as prints and art relating to the time period. As a private collector myself, I am constantly on the lookout for historical memorabilia, authentic photographs, artwork or anything unique relating to military aircraft.
