Here we have a beautiful Helbros with a stainless steel clamshell design case. I'm guessing this is from the 1940's. Everything looks original, minus the new 20mm strap. Dial is a doctor's style. Movement is a manual wind and keeps great time, I do not know the service history. This was an early water resistant style case, with screw in clips, holding on the case back. Very good condition for it's age, ready to wear. I'm asking $150. Ask me anything and check my references. Thanks for looking.
