The  modernist design features an elliptical dial, and beautiful detailing on the gold band. The face is marked PAUL LOBEL.  The actual watch movement is Swiss. I believe Mr. Lobel designed the watch case only. I am unsure about the band, as it is not marked Lobel. However, I believe it to be original to the watch. It is stunning.

I am unsure of the exact age, however, due to the design, I would estimate that this was circa 1960.

Condition:
This watch has age-appropriate wear. The only issue appears to be a missing safety chain. It may have intentionally been removed, but we do not have it.
Watch is running  and keeping time- simply wind it.
