Condition comes first.
Movement condition, prior repairs, corrosion, damage, and missing components matter more than the logo on the dial.
Brands
I'll consider watches of pretty much any make or model, as long as the work is practical, I can get the parts, and it makes sense for you.

A Few Familiar Names
I see inquiries for brands such as Breitling, Omega, Rolex, IWC, Tudor, TAG Heuer, Cartier, and many others. A family watch or an everyday mechanical piece can be every bit as worth discussing as a well-known Swiss brand.
L.M. Campbell, LLC. is independent. I mention brand names only to describe watches I might work on — it doesn't mean I'm authorized by or affiliated with those manufacturers.
Movement condition, prior repairs, corrosion, damage, and missing components matter more than the logo on the dial.
Some watches are straightforward. Others become difficult because parts are proprietary, discontinued, or simply no longer available.
I’ll consider the likely cost alongside market value—and whether the watch matters to you for reasons that have nothing to do with market value.
Send the brand, model if you know it, a few photos, and what the watch is doing.
