Seeking 166.0161 Bezel

Hi all, long time reader but new member.

About a year ago I purchased a 1973 Deville - 166.0161 - stainless steel - mono case
It was an auction purchase with poor photos, but decided to roll the dice.
Thankfully the watch was in pretty good condition, but has clearly been tinkered with - the bezel is missing (presumably broken) and the hands show some signs of abuse.

I was wondering if anyone had any tips on chasing parts up?
Any tips on where to start?

Hard to give bezel dimensions, as I don't have the original, but...
Outer Diameter ~35mm
Inner Diameter ~32mm

Overall its quite similar to this... https://www.ebay.com/itm/184865336148



Thanks in advance!!

One alternative is certainly sending your watch to Omega for service. They will update the hands and they might have or be able to make a bezel.

Thanks for the suggestion - certainly an option..
For simple parts like these, and on a watch that has already been tinkered with I was hoping to source the parts myself.
