The Vintage Wrist Watch Company has dated this piece to the 1920s.
The watch has a stem-winding movement,19 LB T1 where L stands for Lepine (open faced) and B grade.
It is protected by an inner hinged cover.

The watch itself measures 50mm diameter excluding the winding stem and the loop. The case is nickel and it has an interesting winged wheel image on the back, below intertwined initials, perhaps a family insignia. There is some unevenness to the back and a little rubbing to the image but overall the condition is very acceptable for such an early piece. The inside of the case back has the early Omega logo.

The later acrylic lens is in good condition.
The signed white enamel dial has a little damage by number 8 and a couple of chips to the edge which are just about visible as they are mostly hidden underneath the bezel. The larger numbers are a handsome feature of this watch. Blued steel hands, one of them looks to be a later replacement, a subsidiary seconds dial and an outer minute track with red 24 hours numbers.
The watch comes with a single chain which measures 26cm long including the T-bar and the clasp.
The watch will be sent in a new presentation box.
