BWC Chronographe Suisse - Triple Calendar Chronograph

Hi OF,

I was wondering if anyone had information about this BWC Chronographe Suisse (or BWC in general), an extended family member just sent it to me and I hadn't heard of the brand prior to this. Some google searching has gotten me to the Butte Watch Company general information page and I was able to find one other example of this model sold at auction. Otherwise, looks to be gold filled or plated and has a Valjoux 7730. I also have no idea what to do with it so it might make its way to the sales forum at some point, it doesn't really fit into my collection and there's zero heirloom status for the watch in my family, but I don't even have enough information on it to list it. Any information OF could offer would be helpful.

Thanks,
Andrew

Thanks @Dan S , here are more pictures. There aren’t hallmarks anywhere and I mentioned the 7730 since that looks very similar to this catalogue picture but I’d be happy to hear what it really is. Cheers.

That is just superb. Love these triple dates with moonphase.

Thanks @Dan S and @gatorcpa -- very much appreciated. I ended up finding a small stamp between the lugs noting that it is gold plated. At least the plating is in good condition. Will look more using Chronographe Suisse later today. Any idea if these are common enough movements to find parts for since it's not functioning at this point?
