adamska,
This 45 mm diameter watch was designed especially to be worn on most wrists.
The secret is the free-sprung lugs which have suspension mechanism (like automobiles) and 7 degrees of movement on each lug thus up to 14 degrees overall.
I usually set my maximum watch diameter at 42 mm and have been ranting for years at the watch size inflation like the Panerai-Audemars Piguet wars.
The BVLGARI X-Pro is one exception due to the comfort and fit even on small Asian wrists around me.
Finally, the design has even captured the interest of the current Mrs MTF. She usually hates (yes, I used the non-PuristS word) watches with lots of pushers and buttons but the different fusion of materials, textures and colour made her pick it as a 'winner'. She has never been wrong in the past: UN Freak, black diamond trend, brown dial trend, oval shape cases; all picked before they became famous!
You should try one out objectively.....preferably a BVLGARI PuristS 10th Diagono X-Pro but even a regular X-Pro should give you an idea before seeing the BVLGARI P10 launch at IGOTT-2 event.
Regards,
MTF
