Just got a watch back from service at my WM, as part of the service I asked not to refit the very badly worn expander it had on it but I see the watch has fixed solid pins for the strap so the question is how do I go about fitting either a leather or standard solid link bracelet to it? PS the watch is a Roamer MST 372 non incabloc movement so I am guessing a very early movement probably 1944 thereabouts. Its very unusual in that it has a sterile dial, looks absolutely gorgeous, cant wait to get a nice appropriate strap on it so I can wear it Just 33mm across excluding the winder but due to the way the indices and track are made/ laid out it looks much larger even to the point where it looks bigger than a more modern 35mm size..
You can’t have drilled lugs and fixed solid pins. They are shoulderless springbars. Use a pusher tool to get them out and make sure you exit them towards the back of a watch.
But if you don’t want to do that, you can buy open ended leather straps - have a look on eBay This watch has that type of strap on.
Take it back and have those bars removed. Looks like some yutz had them added as I can see the solder joint. That case had spring bars originally.
