2025 Otsuka Lotec No. 7.5 Jumping Hour 40mm
Here we have a quirky 2025 Otsuka Lotec No. 7.5 Jumping Hour featuring a 40mm round stainless steel case that comfortably sits on your wrist with elegant wire lugs. Its soft, rounded, circular brushed flanks lead to a lug-to-lug length of 44.5mm and a case thickness of 14mm, giving the watch an impressive wrist presence. On the right side, at 4 o’clock, a hobnail knurled crown. The flat sandblasted top surface of the case houses the three domed apertures inspired by the old 8mm turret cameras. A circular brushed jumping hour sits next to the concentric circular minutes above the circular brushed running seconds. The engraved Otsuka Lotec motif completes this distinctive jump hour. On the reverse, a screw-down exhibition case back engraved with the watch details around its edge, inside an automatic Miyota Cal. 82S5, 21 jewels, beating at 21,600 beats per hour, featuring a unidirectional skeletonised rotor. The module is created by the skilled watchmakers at Precision Watch Tokyo, a company run by Hajime Asaoka, who also manages Kurono Tokyo and Takano. The entire process is overseen by Jiro Katayama. It comes paired with its 20mm calf-skin leather strap and pin buckle. This watch is sold with its original Otsuka Lotec box and paperwork.
