Third-generation Oceanking (deliveries from October 2023). MONTA Caliber M-22 is a Sellita SW300 built to Monta's specifications (56h, 28,800 vph); Monta says every watch is regulated to ±7 s/day averaged over 5 positions. Some earlier Monta watches used the ETA 2892 instead. Patent-pending 120-click bezel with lumed capsule pip; insert is ceramic or aluminum depending on variant. Flat, bevelled sapphire with 7 layers of AR on the underside. Screw-down crown with guards; solid engraved caseback. Some reviews list 40.7mm / 47.4mm / 11.7mm (pre-release figures); the brand's current page gives 40.5 / 48 / 12mm. Bracelet: three-link (Worn & Wound), fully articulating, screwed links ("no collar pins"), solid end links, two half-links; aBlogtoWatch notes it has no quick-release. Clasp: six-slot quick-adjust with ceramic ball bearings and a flip lock; Monta calls it "on-the-fly" and says it can be adjusted without removing the watch. Monta gives a 3mm slot pitch (2021) but also "10 millimeters of total adjustability" for the six-slot clasp, so range is left blank. Taper and weight not published.
