I have just received back an Ocean 1 Ceramic from Steinhart.
July 2015 model that had stopped, emailed Steinhart and was instructed to use their FedEx service, watch was collected the same day, slight issue with customs clearance as I had not completed the waybill correctly but sorted out by Steinhart, constant email update's received and watch back as new within a week - extension spring replaced.
All this, including FedEx, free of charge !!, truly exceptional customer service.
