i think the seller does'nt know himself and somone probably wrongly told him this along the way. By the way, the full orange bezel model of this was mostly on the Movado version of this, from my recollection. Does anyone about this aspect?
Agree there is almost certainly a Zenith 146HP in there. This model existed in a Movado version, but I believe the Movado with rotating internal orange bezel is also quite rare. Pic from an eBay listing: If you go stealing photos off the web, as I have, most of what you see is this version with fixed internal tachy ring. For timing submarine races.
OK, guilty. Over-paid or bought too early, but it's the only one I've ever seen for sale and it's so... so... Dennis, help me out here...
