I have a Sinn-branded 1550SG that I'd like to have serviced as the chronograph no longer resets exactly to 0 and the service history is unknown. I spoke to the US Sinn importer recently and he said that parts are scarce for this watch and it should ideally be sent back to Sinn Frankfurt for service. I had a less-than-stellar experience servicing a watch at the Sinn factory last year and would prefer not to ship the watch overseas if it's not absolutely necessary. Can anyone suggest someone state side who could service this watch? I've got an email out to Craig @ Chronodeco but thought I'd ask for other suggestions in the meantime in case Craig is unable to work on this for some reason.
