I think it may be 1929 Envoy like this
Agreed, certainly looks to be a 1929 Bulova Envoy. Shame about the case back. I've seen way too many 1920s with this issue. Probably the main reason why Bulova stopped producing hinged cases later in the 1930s.
Nice watch Pedro, Envoy.
I agree. I think it's Envoy. The watch was very damaged and I had some problems with the movement although finally was repaired using a new complete balance wheel.
