Roamer on the whole didn't use model names at this point in its history. It did have some model names, but on the whole most watches were not named, and your watch would fall into this category. If your watch is original - and with watches from India this is never clear until the movement is checked. The movement of course should be the MST414.

You can read more about the case on trims excellent site, and check the history page too.

Thanks so much. Weirdly enough I couldn't locate this very same page before. So from the links, here's what I can gather about the watch:

Model: 414 -1122.005
Movement: 414 Calibre
Case closing method: Waterproof
Material: Stainless Steel
Style: 005
Date: 1961-1973

Considering such a wide range of dates for the 414 movement, I suppose there isn't an easy way to determine the exact year of manufacture, but thank you so much for the help.

 

Hi Rahulg,
I think the model number you quote has possibly been added to the case at a later date than the original watch -and not by Roamer themselves or it could just date to close to time when roamer changed their watch case design and started giving more detailed model numbers to their ranges, This was I believe around 1965/66.
Maybe they assigned a number to it as they were using up old line cases as the engraving looks pretty well done.

This style of their waterproof case was in use from around the mid 1950`s until the mid 1960`s when they also changed their logo to the lower case "r" on their dials.

If it`s the genuine Roamer case you can access the movement by easing the main body of the watch through the bezel from the front.
The crystal sits on a lip on the watch and can just be lifted off.
The dial looks in good condition..the hands may possibly have been replaced though.

The website that Mirius mentioned is a great guide for us Roamer fans though

This is a type-IIa case, probably mid 60s, maybe a little later. But it is a redial, which is throwing things off in terms of dating as some cues a are lost. The hands are not original. I am unsure of that added engraving, I have to look at some examples that I haven't got around to putting on the web yet - but I think I have seen this before, but have not looked at the example I am thinking of for a long time.
