Thanks for your kind words.
The DWO was specifically designed for the PF 5711 and BP Aquanaut 5167 (in addition it also fits the KMF 5167).
So it doesn't fit for the MKF 5711 (V5) nor other currently available 5711's as this wasn't the purpose.
BUT there will be a JJF DWO in the near future.

Regarding the Calatrava - i don't see the need for a DW upgrade there as the stock DW looks decent and some members got a perfectly aligned DW so i assume the misaligned ones were only QC issues.
I didn't hear from anyone who tried to put our DWO into the ZF 5167 nor the Clatrava and digital measurements are not always the most accurate as it depends on 0.0xx mm when it comes to DW's.
hope that helps in all its depth and summarization
