The watch looks very little used, in excellent visual and mechanical condition. Everything looks original. Mechanically flawless, the balance works very strong and watch keeps the time very well (+11 sekonds per day on/off my wrist - straight line), rotor winding smoothly.

Visually by the case shape and dial - it reminds me of the Nivada Grenchen (Croton) Aquamatic or later Antarctic models. It is a little smaller but it is great on the wrist.

The watch is from the late 1950s or the beginning of the 60s, the luma filling is radium.

Service history is unknown but definitely not needed.

A good quality new NATO Vintage Bond Geckota strap included.
