I've been on the hunt for Jaeger 4ATM for some time now. If you don't know much about this piece, there's a comprehensive write up by Boris on his blog . I won't go into detail about the 4ATM as I will let you read the link. Since Boris wrote his article last year, I have been trying to get my hands on one of these. At the time of writing little was known about the 4ATM in terms of numbers and origin. After some late night searching the interweb, I found an interesting blog post written in France which filled in the missing piece of the 4ATM puzzle. The Jaeger 4ATM was manufactured in France by Dodane along with various other watches. Only 500 pieces were made for various brands, mostly French in the 1970s. They all have the following in common 1. Singer dial 2. 41mm case - sometimes marked on the inside of the case back "Belmont Industries Inc - France" 3. Unsigned Valjoux 72 movement 4. Large aluminum bezel 5. Polished steel hands 6. Lollipop centre seconds hands, with the exception of the Jaeger version. As luck would have it, I found myself a Diese 4ATM. Diese is a subsidiary brand of French horologer Duc Oger Paris. When the watch showed up, I was surprised to see that the case is identical to the over sized Compax. I have also landed the inverse panda dialled Clebar. Most people would associate this brand with Heuer but this is clearly not the case here. I'm not for one minute alluding that Dodane made the oversized Compax for UG. The Compax is likely to have been made in the mid to late 60s. It has a signed movement and case and whilst fairly similar is from another league given the quality of the movement and overall package. Its unlikely to have been produced in a run of 500 watches with unsigned movements. Some unanswered questions if anyone can help 1. Who is Belmont Industries Inc? 2. Have they supplied cases to UG. I could not find anything in Sala to confirm that they have/did. Pictures (C) and courtesy of Boris, JG, and I. Enjoy.
