Angelus is owned by Citizen, which also owns Arnold & Son and La Joux Perret. The latter being a movement manufacture, giving Angelus automatic access to a team with know-how and capability to manufacture very sophisticated movements.
The Angelus caliber A100 which powers the U10 Tourbillon Lumière is hand-wound and has hours, minutes, central dead beat seconds (tics like a quartz watch), a 90-hour linear power reserve indication and a one-minute flying tourbillon. The movement bridges and plates are in nickel-silver that is bevelled and polished. It beats at 2.5Hz (18,000 vph) and has a screwed balance with a Breguet-overcoil.
The A100 movement is housed inside a very unique rectangular-shaped case with seven sapphire crystals. On the right, the tourbillon can be viewed from five sides in its own exhibition case, as it oscillates. On the left, is the crown and the timekeeping dial which is made of a translucent-grey sapphire crystal with a black outer ring and transferred markers.
The case measures 62.75 mm by 38 mm by 15 mm and is made of BO-988 annealed stainless steel, which has higher corrosion resistance than the 316L stainless steel.
Angelus spent four years creating this masterpiece whose name was inspired by light (lumière in French). According to Angelus, “The clean, modernist displays pay tribute to Angelus’ acclaimed travel clocks as well as taking cues from iconic industrial designs and designers of the 1960s and ’70s.”
The strap is hand-stitched in black alligator leather with a stainless steel folding buckle. Limited edition of 25 pieces. (Ref. 0LUAS.B01A.C001F)
