Aegir is a niche watch company. Todd Caldwell who was a commercial North Sea diver designs and assembles his very high quality dive watches from European made cases and movements in his home town of Perth Australia. So sending a watch back for servicing is a potential issue. Sean solves this problem, he has just repaired a winding stem issue on my Aegir CD 1 which has a very rare and unusual movement from the Swiss Mhvj company. Sean also adjusted and regulated my Aegir CD 2. Both watches are now working perfectly for less than the cost of shipping them back to Australia. Sean also recommended not fully servicing the watches now but waiting for a couple of years as the movements in both watches are running smoothly. Minor work or full service, Sean is totally recommended.
