I have just finished this 1927/28 Roamer 15 Jewel Sterling Silver 'Paris Square' 'Trench' watch:
I bought this just recently in a job lot, along with a 1915 Waltham. The Roamer jumped what must be close to a 3 year long service queue and I sorted it out today. It arrived non functional, but in OK condition considering it is 85 years old. I was pretty pleased with the dial when that horrible yellowed crystal came off.
This image shows the condition of the hands and dial. When the crystal is missing or yellowed like this one was, I fit a temporary (cheap plastic Indian) crystal to protect the dial and hands while in storage as the old yellow crystals can lead to corrosion of the hands.
The movement needed some work, a new dial side jewel for the 4th (seconds) pinion as the original was fractured (very common) plus a new setlever screw (thankfully I had a generic from an old selection that was close) and of course mainspring. Gratuitous photo of the finished MST175 movement.
The hands, cleaned, lightly polish and having just been relumed.
Dial cleaned, dial lume is the original radium - with an old repair to the '7'.
Happy with that.
Wristy Sadly the old croc strap is just too fragile to wear.
