Countersinking Required to Fit a Gen Daytona Crown Tube

[freddy333]

I just finished installing a gen triplock crown and crown tube in Josh's 116509 Daytona and wanted to alert other modders who may be considering the same mod of this model that you will need to countersink the crown tube hole in the side of the case (I used an 11/64" Titanium coated bit) to allow the crown to sit flush when screwed down into the closed position. Unfortunately, I did not realize this until I put the watch together, so I will be taking everything apart again. But it is all worth the extra work because the watch looks and feels a bit nicer with the gen parts.
