I'm trying to find out what size chrono button wrench for screw down button for a tudor chronograph, big block case... I think it's 3.05mm ? but not sure. Same as daytona of the same vintage ? I'm actually looking for the screw part that triggers the chronograph. It has a groove for an O-ring. It looks to be brass. If anyone has one you want to sell, I would like to purchase it. Otherwise I have all the other pieces. Thanks in advance for any help. Please email me at
