Hi,
Looking for a bit of help…
I’ve recently inherited the attached watch and looking for some info in it?
Year made….rough valuation for any watches of that type….what does the small T on the watch face mean….and what does the info on the back all mean.

Any help would be greatly appreciated.

regards
Ross

Welcome, that s a fine and rare military-issued SM 300, probably end of the 60ies! Congrats!
No "big triangle", but the T is IMO on the right place.
Except the bracelet, IMO all original. Don t let any jeweler change or polish anything or ask us here, before a service.
atb !

Wow 😲

There’s a fantastic forum on military watches and I’ll start a thread there that links to this thread. It’s members only but maybe you could register. Don’t do anything with it until you fully understand what you have. It’s a very valuable watch.

Thank you for your advice and I will take it onboard.

Here’s a link to a thread I just started. It’s really worth working out how to register over there too. OmegaForums and MWR are pretty much the best two watches forums on the internet for fairness and honest advice. Good luck whatever you decide to do.

Year made..

One would think around 1966 but issued in 1970 according to the caseback.

….rough valuation for any watches of that type

A lot

….what does the small T on the watch face mean

Military marking meaning the dial lume is tritium.

….and what does the info on the back all mean.

Thats its military provenance.

0552 Royal Navy

0552/923-7697 A/311/70 , is Royal Navy 923-7697 for the NATO code, military wristwatch, watch number 311, issued in 1970.

The following year the navy switches to the Milsub by Rolex..

wow, what a find! As advised, take your time and don't rush anything. You have a real gem here! Congrats!
Do you have more info about your great uncles? Maybe pics of him in the Navy? Would even add more to the whole package 😀

The value is in the originality of the watch, even though some parts may have some damage from use (e.g. the bezel). So do not change anything. Go slowly. If you want to use it, then you will want to find an experienced watchmaker to service the movement. Otherwise, don't do anything at all.

Listen to what people tell you. You might receive emails with offers to buy. Ignore them.

Don't take the watch to any watchmaker or anywhere for the time being and don't wind it if it has been sitting for a long time.

As mentioned MWR or Military Watch Resource is the best place to post and ask your questions on the watch.

It is valuable, so place back in your drawer and don't show it around to anyone. Even people you know.

This is a highly sought after vintage military watch and valuable. Proceed with caution. If you get the watch serviced, you will only want the movement serviced by a competent watchmaker of high repute and nothing else touched. If you don't need to sell it, definitely hang on to it.

It seems not to have fixed lugs, a specified requirement by MOD. Not sure that bracelet could be used on fixed lugs.
The assignment over a plain/erased back was quite common in that date range

You've gotten all the advice you need already. If you are in the UK, I'd contact Simon S at Watches of Knightsbridge. He runs an excellent auction house that specializes in military watches. I have purchased a number of things from him and always found him to be honest and reliable. He will help with a candid valuation and guide you through any necessary repairs. If you are in the USA, see Adam Victor at Christies. Best, Hurley

Christie's will not be your best bet. Use Phillips in Geneva.

WYW -- I'll disagree with you a little there. Philips Geneva and I are very old friends... 😀 However, Mr Bacs does not have much interest in military watches and the Phullips Geneva auctions do not often feature interesting military pieces -- or IMHO promote/catalog them well when they do. For Phillips, our lucky legatee would be much better off contacting Paul Boutros at Phillips NYC. He is truly superb all around, but is especially good with military watches. I agree that Christies has been second rate lately. But Adam Victor has taken over the NYC team this month and is a fabulous guy and one of the world's great experts on military watches. There is a fascinating story on him in Hodinkee this week. Having said all that, Simon S at WOK would also do very nicely for our new friend if he is UK-based. Your mileage may vary!! All the best, Hurley

The aim with such a watch is preservation not restoration. The advice offered here is really worth hearing.

Ross, have a very close look at the place, where your metal band connects to the case. these military variants should have a fixed metal rod, which is not removable. your band could be modified to keep them in place. or do you see some kind of a shiny steel spring bar, that connects to the holes in your case? and can be removed ( it is spring loaded ) that is quite important for originality.
