The Bulgari Diagono Tourbillon is 42mm in diameter with angled lugs which made it very comfortable on my small wrist. The case and deployant clasp is made of platinum and even though it was on a crocodile strap it still had a hefty and solid feel to it. The Diagono case is slightly thicker than the regular BULGARI-BULGARI case ( I don’t have the exact measurements) but it easily fit underneath my shirt cuffs without snagging.
The carriage of the tourbillon is made of 56 individual parts. The tourbillon bridge is brightly polished and chamfered on the edges.
The Bulgari Diagono Tourbillonwatch??houses the BVL200 manual wind movement which consists of 200 parts, with 20 jewels and beats at 21,600vph. The caseback is fitted with a transparent sapphire glass to show the movement. In addition to the clear view of the tourbillon, there is a power reserve indicator with up to 64 hours of reserve when fully wound. The signature BVLGARI-BVLGARI logo frames the movement.
I just noticed that after posting the pictures that I didn’t remove the plastic protective sticker that was on the caseback (well actually I’m glad I didn’t remove the sticker so that the lucky new owner can have the pleasure of doing this when he or she picks up the watch? ). So all the little specs and dark spots are from the air pockets in the plastic sticker, so rest assured that the finishing is of high quality. Anyway, you can see that there are nice little details in the finishing of the movement parts. For example, the wheels have a satine soleil sunburst pattern on them. The power reserve has a cloud de Paris guilloche pattern on the inner section of the scale. The main plate surface is not the typical Cote de Geneve, but a hand applied finish called Traits-tires.
Even with the case crown protectors protruding more than half way to cover the crown, the crown was easy to activate. I don’t have that much experience gauging the quality of the movement by turning the crown, but it felt very smooth.
This was the first piece in a limited edition of 30 watches. The series numbers were engraved on the 9 o’clock side opposite of the crown. It’s a minor detail but I would have preferred to have this somewhere more discreet like on the caseback instead of the side of the case.
The Bulgari Diagono Tourbillon comes with a crocodile strap with brownish stitching. In most pictures I’ve seen of this watch and one Bulgari website it is usually paired with a black strap. The deployant buckle is also in platinum and has a brushed finish on the flat surfaces and highly polished finish on the side edges.
