Thoughts on this Seachero?

Yep. Looks like a refinished dial

Yes, the dial is no good. Can't believe it's not disclosed actually, it's so bad. Well, hopefully the bidders know what they are doing. There's value there without the dial.

Yes, really poor quality redial.

An authentic Seachero in good condition will cost considerably more than $390. Here’s mine for comparison:

I'm not sure that you can properly refer to reference 2937 as the "real" Seachero or a Seachero at all. I think that it's generally accepted that there is no actual "Seachero" model in the Omega catalog. The conventional wisdom is that the term is applied to watches having the Ranchero 2990/2996 case with a Seamaster dial. As with the Ranchero, reference 2990 is the subsecond version and reference 2996 is the sweep second version. The only difference between the two is that reference 2996 has a domed case back to accomodate the slightly taller sweep second movement. Reference 2937 has an entirely different case and was introduced in 1956, two years before the Ranchero was introduced in 1958.

Sorry, but I respectfully disagree. The 2990 and the 2996 cases are the same, but the case back on the 2990 is flat and the case back on the 2996 is slightly domed. Typically, the 2990 houses a caliber 267 which is 4.05 mm tall. The 2996 typically has a caliber 284 or 285 which is 5.1 mm tall and that's why there is a domed case back on the 2996 - because the taller sweep second movement won't fit with the flat case back that's on the 2990. Regarding my point about what is a proper "Seachero," you want to use that term for a model that was introduced two years before the Ranchero was introduced. "Seachero" is generally understood to mean a Ranchero 2990/2996 case -- which the 2937 is not -- with a Seamaster dial. Also, there are EOA's which describe watches with a 2990 case and a Seamaster dial as a "Ranchero Seamaster." Here's an example of one belonging to a watch that was offered for sale on OF by Kiwibloke:

I am not aware of any such EOAs that link a Ranchero case to a Seamaster dial for reference 2937. That's my point. If you're aware of such an extract, I'm happy to be corrected on this point. Don't get me wrong. The 2937 is a very attractive watch and I'd be very pleased to own a good example. I just don't think that it's properly called a Seachero.
