Monta M-22
Monta launched around 2016 with the Oceanking. The brand's M-22 is built on Sellita's SW300-1 — a movement widely regarded as one of the most reliable third-party Swiss automatics available.
The SW300-1 base is itself a Swiss-made alternative to the ETA 2892-A2, sharing its slim 3.6 mm profile and 25.6 mm diameter but built entirely outside the Swatch Group's supply chain. Sellita later introduced an Optimization Barrel that extended the standard 42-hour reserve to 56 hours; current Monta production uses this upgraded configuration, as confirmed on the brand's own product pages for the Noble, Triumph, and Oceanking.
The company tests every watch to a strict house accuracy standard — tighter than an unregulated base movement, though not the same as COSC's -4/+6 s/day criterion for mechanical chronometers.
Within the competitive under-$2,000 microbrand segment, the M-22 offers a well-serviced Swiss movement with hacking, hand-winding, and a 56-hour reserve in a 3.6 mm stack — a practical combination that has powered the Noble, Triumph, and Oceanking across several generations without Monta needing in-house movement development.

FAQ
Is the Monta M-22 automatic or manual?
The Monta M-22 is an automatic (self-winding) movement: a rotor winds the mainspring from the motion of your wrist, so it needs no battery. It can also be wound by hand via the crown.
What is the power reserve of the Monta M-22?
About 56 hours on a full wind — into a second day, so it keeps running overnight off the wrist. Power reserve is how long the Monta M-22 keeps running once you stop wearing or winding it.
Does the Monta M-22 hack (stop the seconds when you set it)?
Yes. Pulling the crown stops the seconds hand, so the Monta M-22 can be set precisely to a reference time before you push the crown back in. Hacking is what lets you sync several watches — or a watch and a phone — to the exact second.
Does the Monta M-22 have a date function?
Yes — the Monta M-22 can drive a date display, though whether a given watch actually shows the date depends on the dial the maker chose, so check the individual model rather than the movement.
