The Ebauches Bettlach (EB) caliber 8810 is a vintage mechanical hand-wound watch movement. This is a Swiss made movement that was produced in the 1950s – 1960s. This is a one jewel movement with a pin-lever escapement.

This movement may be signed with the following text:

Swiss Unadjusted / One 1 Jewel / EB (shield logo) / 8810

Although not easy to read in the picture above (sorry, it was a cell phone pic of a watch someone was wearing), the strap over the mainspring barrel is signed Webster Watch Co., but this may be signed with a different brand depending on who the watch was made for (examples: Economic Swiss Time Manufacturing, Lucerne Calendar, Sindaco LTD, ALFEX LTD, Montgomery Ward, etc.). Either way, if it’s signed “EB 8810” then it is still an Ebauches Bettlach caliber 8810.

Jewel Count

The EB 8810 can be found with various jewel counts. The movement featured on this page is an example of a 1 jewel movement, but there are other 8810 examples with 0 jewels, 17 jewels, and possibly 21 jewels (needs confirmed). If you have a watch powered by the 8810, please add the watch brand and jewel count to the comments below.

Maker Confusion

Sometimes you will see this movement listed as being an Ernest Borel or ETA. This confusion comes from the “EB” initials which some folks think stands for Ernest Borel. The ETA mixup comes from the shield logo which may resemble the ETA logo a a quick glance with the naked eye.

How to remove the crown/stem?

The remove the crown and stem on an EB caliber 8810 movement, you will want to look for the detent button near the stem. There are two round areas that look similar, but find the one that has a slight indentation for your tool as pictured below.
