Looks great Yves. A couple thoughts....
1. I hope it has screws for the strap for easy changing :-)
2. I would suggest a chamfer around the edge of the bezel, maybe 1/4 of the width of the bezel.
3. The matte finish looks great, but for the owner to do their own touch ups for minor scratches, a brushed finish would be a bit more 'user friendly'.
4. Some type of engraving or etching on the end of the crown would be a nice touch.
Overall, a great looking sturdy piece. I'm glad you picked grade 5 titanium rather than the more common and softer grade 2.
Well done!
