Hi all,

I bought a couple of interesting watches of Ebay for a few pounds but can't identify one of them. It needs a new balance spring (if I can find one!!). From research it looks as if i may be an Ebosa cal. 85. There seems to be very few images of the movement and those that are around are not quite the same so I am confused. Could do with finding a watch with he same movement really. It came in an interesting case with a clear back and clear plastic surround with the digits imprinted. The dial has Ginebras printed. No amount of Googling has shed any light on the name.

The movement is fairly small at 20mm

So if anyone out there can I would be grateful. I am new to the forum so I hope this is in the correct forum!

I imagine it would. Certainly the balance staff of the Cal. 86 and the Cal. 87 (looks just the same) are identical according to Ranfft. One main factor would be size - if your movement is smaller than the Cal. 86, it may not fit. Measure it out and see.

I did a quick check on the Jules Borel website, and they show a different part number for the E.85 vs the E86. Which doesn't mean it won't work, just that it isn't exactly the same.

Hi Andy,

it is confusing: The 85 was only available with pivoted staff and impulse pin, the 86 with the same, but also with impulse finger, and with pointed staff. But I guess you can use the hairspring of any. And if you find a donor-86 with cap jewel, you can take the complete balance.

Regards, Roland Ranfft
