When talking about the value of vintage watches (and collector's items as a whole) we have to keep in mind, that the 'value' is what the next collector is willing to pay for it, nothing else (leaving aside material value of the case, often giving the axe to the rest of the watch anyway). And as 'the last shirt has no pockets' and the children often have other interests, the price might be determined at a sale 'from estate'. I recently heared a sarcastic joke at a watch-seminar: There is an index figure determining when you should start selling your watches: (age) x (number of watches) = > 1000, start selling!
Whatever, the vintage ROAMER watches, in my opinion, appear to be somewhat undervalued (if you take the idiotic prices in the present bubble as a benchmark). Especially some of their cases are really timeless.
Shown below, one of my Roamer watches: 1960s model LimeLight Automatic with probably one of the best (most effective) automatic movements around, MST (Roamer) cal. 479 (ETA cal. 2622 f=21,600 A/h). Changing the date is not so effective with the most basic 'quick set': changing between 20:40 and 24.00 (better going a bit further after the date has changed in full to avoid any damages).
When I bought this watch from a lady, I wondered how you can give this watch a pre-wind with the crown so far in. You could also see on the case, that someone has often tried to get a grip on the crown with tweezers or pliers. I asked her, how the prewinding on this watch is done and assumed that it most likely doesn't have the right crown. It was the watch of her husband, so she couldn't answer that question, but she said, that her watchmaker told her that the watch must be worn on the wrist to get the windings.
Well, what do you know? Every automatic watch must be worn on the wrist to get the windings, but I was talking about PRE-winding.
I got it anyway, because I liked the good condition and the looks and in any case, I have my (mostly unused) collection of watch winders.
MY watchmaker told me the same thing. The watch does not need any pre-winding and I soon saw what he meant. Just when taking it out of the box, it starts immediately and after 5 minutes on the wrist, you already have acceptable readings on the timegrapher.
The crown is really just for setting the time and date when pulled out.
The watch got a new, not original but nicely fitting crown (the old one had also suffered profoundly) and a complete service. A couple of hours on the wrist, it has a good amplitude, a beat error of 0.1 m/s and a straight line across.
Roamer also became a victim of the quartz crisis. In the 1990s, the company had been re-activated as a Swiss company in Switzerland under foreign ownership (Hong Kong). Their new products are good Swiss quality in the medium priced sector.
As with all watches to collect: Stay away from any crap floating around on the market and look for specimens in acceptable condition, technically and optically.
My favorites models: Anfibio, LimeLight, Searock and Stingray.
Be aware, that f.i. the Anfibio (with patended watertight case) is a front loader, which means, that a simple look into the movement or and adjustments are something for the experts only, that's why some collectors shy away from it.
