AWCI Certification: CW21 cs CMW

[tunadubby]

Hi,

I have a Zenith Daytona to service. And after hearing the price quote from RSC, I leaning towards finding an independent. My top two candidates are both AWCI certified. However, one of them is CW21, the other is CMW.

Common sense says that the CMW would be a better candidate. However, the CW21 guy was more passionate and seems genuinely excited to spa my watch.

How much more weight should I give the CMW certificate?

Thanks!
