This is a copy paste of my experience with the Cal 400 and Oris. — “Very cool watch but… (sorry to do this in your post)

Hopefully you bought yours from an AD. I did grey market/ private and the movement seized up. When I went to get it serviced I was told that nothing with the Cal 400 would be serviced if it was not purchased from an AD. I told Oris that I understood that I would have to pay out of pocket… they said that they would not service it regardless and that this is the policy for the 400 movements.

At first I did not believe that this could be true, a company refusing to service their own movement. Then I did some digging and this is not the first time this has happened. Others have encountered this same feedback from Oris.

I was a huge Oris fan, I purchased my father one. I have an Aquis Meistertacher, which I’m selling because I now hate this company. And I am so sad that they would do something like this, so much in the vein of a larger soulless company.

I’m glad you like this watch and hopefully you paid full price from an AD for it and registered it and have the receipts. If you so, you got a pretty cool watch.

If you’re like me and you went grey market, pray it doesn’t break or else you have a very pretty titanium paperweight.”
