For sale is Universal Geneve bomb timer. Those time were made in 2 variations (see pic from the Sala book). The left one in the Sala book appears to be reference 39.901 and has serial numbers somewhere between 695.xxx and 841.xxx. About 17 of them were seen at auctions and sales in the last 2 decades. Mine is the right one and I have not seen other examples for sale. This one has a marking 92.749 in the case back. On the edge of the case 749 is punched. The moment appears to be a Valjoux 067 of which no info is to be found. My watchmaker thinks it is a modified high beat (36.600) pocket watch movement. Watch runs and had a service. Costs for this service were EUR 1.000 and I was lucky this amount was capped otherwise it would have cost more. The case size is big with 55 mm. My asking price is EUR 5.000 ONRO. Bank wire only (too much scammers around..). No trades please. I live in the Netherlands and have solid feedback (see: Ebay mark020, TZUK and Horlogeforum.nl). More pics upon request.
