The date hand comes with a red arrow.

The watch comes with an automatic movement with caliber Felsa 693 Bidynator. It has a brown leather band.
There is not much information on the company Ultramar and its trademark. It has been registered in the US and Switzerland in the 1940’s and 1960’s. It seems also that the company promoted its Swiss movement, which indicated that the trademark was used to market Swiss watches, probably in the US.
