1. “Leonidas Watch Co. ” was very active in the production of aeronautical timepieces and in the
design and production of dashboards for aircraft . The 3rd Reich in general and Luftwaffe in particular
were one of the major clients of this Company. It is plausible that the watch shown below , with a particular
caseback , is the one supplied to Luftwaffe .
2. The caseback of this watch is particular because it does not have the 6 notches like the other D.H./D. but
has another unlocking system for access to movement.
3. The Leonidas is a rare watch . In 20 years I have recorded 10 watches , of these , 4 are marked “D.” , the
others 6 “D.H.” . But , while the “D.” have the same characteristics ( also of the caseback) and a
plausible S/N ( 37XXXX/39XXXX) , the D.H.s , despite having the same case , dial, and movement
of the D. , they show very different casebacks and , above all, extremely varied S/Ns.
This leads to think that DHs may be “marriages”. As proof of this , below are the photos of a
Leonidas DH purchased in 2001 . Case , dial and movement are correct while the caseback is of a Helios DH .
