I can see why you’d have trouble btw the Aquastar and Vulcain.

Personally I’d pick the Vulcain (because I don’t feel I can pull off the look of the Aquastar), but if you like them equally aesthetically, the Aquastar is better value of movement and has a bracelet option.

I like the design but have an issue with any watches where they hour and minutes don’t touch the markers.

It may be an aesthetic choice, but makes me feel like the watch design is trying to hide an inaccurate movement. Plus I can’t tell the exact time.
