My watchmaker believes there’s no appreciable difference in the quality of OEM case back gaskets (like for a Speedmaster), vs whatever generic equivalent is available in the same specification. Agree or disagree?

Is there a big difference in price?

Yeah, OEM $12/gasket. Seems expensive. Aftermarket a few dollars at most.

Why gamble? It’s not the cost of the gasket it’s the potential cost of water intrusion.
