Do you know which movement is inside? But by the bezel engraving looks to be an old v1 or v2 Avenger by H Fac. V3 has the better engraving on the bezel and in my opinion is a super rep. Still a very good catch!
It should be a v2 HFac (the v1 has a larger lume area on the 12 o’clock, 6 o’clock and 9 o’clock markers). Breitling script under the wings is different on v1 vs. v2.
here is a photo of my v1 (you can see the lume markers are different on the v1 vs. the v2).
Owned a swiss eta H-fac V3 with grey dial, too. Absolutely a super rep! My watchmaker wasn’t able to spot it as a fake without opening the caseback.
The watch of the TS seems to be a V2 imop.
