I'm now on a search!
What grades of titanium have I owned? This is not a question that has troubled me in the past.
Here's my titanium watch ownership history:
Omega X-33
IWC Mark XVIII Hodinkee
IWC Aquatimer 3719
F.P. Journe Octa Sport
Sinn EZM1
Tudor Pelagos FXD
Search tells me that the Journe is probably Grade 5.
Tudor is probably Grade 2.
X-33 is probably Grade 2.
Search tells me that Sinn uses both, but not yet which one was used on the EZM1.
IWC I haven't found yet.
