any recommendations would be appreciated... I know some watchmakers avoid these like the plague...

thanks in advance,

I thought someone with more expertise would chime in but I'll throw this out to you.

Try contacting Jack at Superior Watch in New York. He serviced my Porsche Design Lemania 5100 and did a great job. He has access to parts and had great knowledge regarding the serving of the 5100 movement.
