This tool has been specifically developed to safely open manual winding Tissot PR 516 watches (vintage 34mm case). These fit a 10-sided caseback and measure approximately 28.9mm across flats.

It has been developed to match generic Rolex/Bergeon style case openers and will fit Rolex adapters for the 5700 universal case opening tool. 

The case opener is custom 3D printed to ensure a good fit and is printed from durable plastic which will open tight case backs while eliminating the risk of scratching associated with generic metal tools. The handle is printed in black and the die is printed in iron grey.

Due to the 3D printed nature of these parts, there will be visible layers as shown in the pictures. If you are in any way unsatisfied with this product please do not hesitate contact us.
