Watch identification

Good morning everyone.

I'm looking to get some guidance and information from people who know more than me!

My name is Sean, I'm 37 years old and work for the NHS. Back in 2006ish I did a favor for someone and they very kindly gifted me this watch.i wore it a few times but mostly I kept it safe because I liked it and didn't want to damage it (I worked a different job back then) I've gone and looked at a load of different websites but I failed to find what model the watch is. It's reminiscent of De Ville Prestige Tonneau, but it uses 10,20,30 ect instead of Roman numerals or numbers. The placement of the date sits above the omega logo, which isn't very common. And on the back there's a reference number which doesn't seem to be bringing up any information in databases. The watch has a good weight to it and his automatic.

I know that the next step is to go to someone to get it opened up.

Any information you can provide would be greatly appreciated.

Thanks
Sean

Try google DE VILLE TONNEAU AUTOMATIC JUMP HOUR STAINLESS STEEL. For the exact model, maybe you have to open the case back

Thank you both. It's good to know ☺️
