1950+ Spiedel was a popular metal expansion watch band choice. Longines was a popular w.w. choice as well. Here is a good one in original box. Gold watch case has nice qualty little diamonds. Band is loaded with real diamonds, but cheapest rough cut dirty ones. Never knew Spiedel made a diamond band. Seller and I never thought it had real diamonds. Total cost was less than 10 U.S. gallons of petrel.
