The case looks like a Hugunenin Frères you find in the Omega Seamaster / Railmaster / Speedmaster first generatio, or the Jaeger Lecoultre Deep Sea Alarm.
The nice detail ,the date which is red and black depending on the day, like the Rolex GMT MASTER 6542.
A pleasant balanced dial. A strong looking watch.
Enjoy the pictures.
Best,
Nicolas
