Angelus has just added the new limited edition Angelus U553 Tourbillon Volant to its Urban Collection. A skeletonised dive watch with a tourbillon, it is not their only diver tourbillon (U50 Diver Tourbillon and U53 Diver Tourbillon) but, at 46mm, a fraction bigger than the other 45mm-sized cases.
The case features a helium-escape valve at 9 o’clock, at 2 o’clock, the screw-down crown, which controls the 60-minute graduated rotating unidirectional flange. At 4 o’clock is a second screw-down crown for winding and setting the time.
The case is in grade 5 titanium, with a thickness of 12.4mm, and is water resistant to an impressive 300m. It has a helium escape valve at 9 o’clock, and a screw-down crown at 2 o’clock which controls the 60-minutes graduated rotating unidirectional flange. At 4 o’clock is another screw-down crown is for winding and setting the time.
The dial features the industry’s currently popular green (this time lacquered khaki) on the rotating flange. The indices on the flange, and the hands, have Super-LumiNova. The barrel is located at 1 o’clock, one-minute flying tourbillon at 6.30, and small seconds at 9.30.
The movement is the same as the one in the U50 Diver Tourbilon – the manual-wind Angelus in-house skeletonised Calibre A-300 which beats at 28,800 VPH and has a power reserve of 60 hours. In terms of finishing, the plates and bridges are sand-blasted, wheels circular-grained, and of course the tourbillon cage has bevelling and is hand-polished.
Coming on a green rubber strap with a titanium pin buckle (plus an additional hand-stitched green NATO strap with titanium pin buckle) and in a limited edition of 25 pieces, it has an RRP of CHF 39,400.
