Repair IWC GST Titanium in Holland

My watch is having some issues and loosing some seconds (maybe a minute every
1-2 days),

I live in Amsterdam and I'm looking for a repair shop that would fix the
problem.

I could bring it directly to IWC but I'm one of those IWC owners that have the
watch but not the money....
do you recommend anyone in the Netherlands?

Please supply your email address, and I'm sure members here will be happy to
recommend a competent IWC repairman privately.

Thank you!
