Happy to share my experience:

I had this model in steel, and the main issue for me was that it did not sit comfortably on my wrist - it felt top heavy and not comfortable. I used it on the steel bracelet and on the sailcloth strap with tang buckle - neither worked for me well. I did not try it with the deployant clasp though, so I do not know it this could help resolve the comfort issue. Based on that, I think the gold version would be worse in terms of comfort and the titanium one could likely be better. Another issue I had was with accuracy: mine ran at +10 sec a day, which I did not find satisfying. But mind that I had the previous version that came without a silicon hairspring and at that time they regulated them in 5 positions vs 6 positions now.

I have had two both steel versions. The crown came off on the first one and on the second one the bezel spring broke. I moved on to a sea dweller and has never looked back.
