Service: Roamer With an MST 414 Movement

I bought this Roamer on eBay to restore. I don’t do that as much as I used to but I still like to have a project watch to work on every now and then.

Like most Roamer watches, it has an in-house movement. This particular watch is powered by the MST 414 which has a micro regulator so it can be regulated very accurately.

The movement, the ‘R-logo’, and the fact that the case back has the Swiss cross and 4 patent numbers indicate that the watch is from 1966.

If you look closely, you’ll also see “Pm” just right of the number 6 on the chapter ring. That stands for Promethium, a lume that they used in the 1960s after they stopped using Radium and before they started using Tritium.

The winding of the crown was difficult and the crystal was damaged. The watch did run but it needed to be serviced and regulated.

How to Remove a Broken Screw With Alum

Have you ever had a watch movement with a broken screw? Or an original signed crown (case parts are often harder to find than movement parts) with a piece of a broken winding stem inside?

Sure, you could use a drill to drill out the broken screw or use a screw extractor. 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 tools.

How to Fit a New Acrylic Watch Crystal

One of the advantages of acrylic crystals is that you can easily polish away scratches to make the crystal look like new again.

This is especially useful if your watch has the original signed crystal or a crystal that’s not easily available anymore.

It’s better to use the original parts if possible. However, sometimes the damage is just too severe. If the crystal is cracked or chipped, there’s no other solution than to fit a new crystal.

With this guide, you’ll learn how to easily fit a new acrylic crystal yourself.

Service: Caravelle With a Bulova 11DP Movement

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.
