Have you ever had a watch movement with a base plate that had a broken screw? Or an original signed crown (that is impossible to find nowadays) with a piece of a broken winding stem inside?
Sure, you could use a screw extractor or use a drill to drill out the broken screw. However, not everybody has access to these tools. I don’t, for example, because I don’t often need them and they’re expensive.
But I have some good news. There’s a trick to remove a broken screw without using special equipment.
The biggest advantage of acrylic crystals is that you can easily polish away scratches to make the crystal look like new again.
But if the crystal is cracked or chipped, there’s no other solution than to fit a new crystal.

This is a regular service of a Caravelle dress watch.
Caravelle had links with Bulova (Bulova’s less expensive line). The movement is the Bulova 11DP which is a rebranded Citizen 0241 movement.
This movement was available in two versions. One has 7 jewels and the other one has 17 jewels.
When you remove the case back, it’s a bit disappointing to see that it’s the version with 7 jewels but it works. Actually, it works great because, after the service, the amplitude is 270 (which is very good for a citizen), with a beat error of 0.3 m/s and a rate of +4 sec.
This is a first! A Russian watch on WahaWatches.
A lot of professional watchmakers don’t accept Russian watches. Either because the parts are hard to find or because the movements can be a bit flimsy.
However, it’s my experience that Russian movements perform quite well despite them being cruder than Swiss counterparts. You can buy a lot of parts on eBay if you need any.
This watch is a Start with a ZIM 2602 movement, similar to the LIP R-26. The ZIM has 15 jewels and no shock protection system but it does have a Breguet hairspring, just like the French movement it was based upon.
The upper part of the case with the lugs, bezel, and crystal is one part. The case back with a recess for the movement is another part.
The movement with the dial is directly fitted inside the case back.
