This is a nice vintage watchmaker or jeweler caseback opener tool and wrench for the Bulova Accutron 214 and 218. These are the genuine and very collectible wrenches that were made by the Bulova factory for use by repair facilities both in the Bulova factory itself and by authorized Bulova Accutron service centers. If you own or collect Bulova Accutrons, you know how difficult it is to find a qualified repair person or watchmaker to work on them these days. Why not save yourself some hassle and get a case wrench so that you can take a look at the movement for yourself before having to hassle with sending it out for evaluation? Don’t risk using a generic opener on your Accutrons! One slip and you can really scratch up and/or damage your valuable watch. It’s just not worth it, especially when you can do it the right way just by getting a single tool.
The tine at the 3 O’Clock position is missing on this wrench. I can’t tell if it was intentionally modified by the watchmaker or if it is broken. In any case, it works great on both 214s and 218s–I’ve tried it! There’s no wobbling or instability due to the missing tine at all. There are the usual minor scratches, but no corrosion or pitting. Other than the tine, the tool looks to be in excellent condition.
