0004  Rubens

From photos. Caseback is engraved 'STAINLESS STEEL BACK - WATER RESISTANT - ELECTRONIC ... TESTED' with a figure engraving in the centre, and has slots around the rim (screw-down back, case has a thread). Movement has a plain nickel plate with large gilt wheels, no visible jewels, no rotor, and a small stamp that looks like 'MAM' (reading unsure); no calibre number seen. Looks like a basic budget movement. 'Super 21' and 'Navy Time 200' are dial marketing text and do not confirm the jewel count or any water resistance rating; do not rely on the water resistance, the gasket is old. Owner reports it winds and ticks. Dial lume and crystal are aged and scratched.
