Has anybody any idea what the original strap was like on my watch please ,it must be a strap type as there are bars not pins that hold it in place.also i had it serviced by Omega about 5yr ago costing £520 and it used to be a screw down crown but they changed to to a push in type and why would they do this,thanks for your help

 

The numbers on the back are military markings. The "W10" portion at least means British Army. The rest of the markings have further meaning about the watch, but I'm not very familiar with what they all mean, and I'm sure that you can google it from here to find the rest of the meaning.

As to the correct strap for this watch, I am not sure. We have some members here that are extremely knowledgeable on SM300's so maybe one of them can help with that, and the non-screwdown crown. If this watch has fixed spring bars, I am assuming that it is in relation the to military markings on the back. Many watches intended for military purposes had fixed spring bars, as they were considered stronger and less likely to fail. At least, that is my understanding.

Lastly, did Omega happen to return you any of the original parts that they replaced during service?

 

i hope you got them back :/

 

Presume the fixed spring bars would have used a nato strap - much more secure, as you wont lose the watch if one bar is ripped out

 

No they didn’t ,i‘d got water inside it and hadn’t used it for years

 

So typical Omega, trashing rare parts.

 

Thanks just ordered 1

 

and Rolex and Patek and everyone else that inhouse services their watches.
