Diesel Watch Backcase Opener

I had to replace the batteries (Yes there are 4 inside) of my Diesel DZ-7313 watch without having special tool nor purchasing it.

Everything started year ago with the opener I designed for my Ice-Watch → https://www.printables.com/model/134206-ice-watch-backcase-opener

This model was inspired from the following design →  https://www.prusaprinters.org/prints/131876-columbia-ca025-e15-watch-backplate-tool published here 

This time the inner diam is 56mm. Pins are the same than the Ice-Watch (2mmx1.6mm / Qty 6) so easy. I just had to pay attention to the thickness of the opener as there were not a lot of space between the back-case and the watchband support

Printed with Recycled PLA from SAKATA 3D with variable layer heights (0.10mm for the area with the pins and 0.20mm for the rest)

Note that the Diesel DZ-7313 watch needs 4 batteries of 3 different models. 1 x Renata 364 for Timer 1 / 1 x Renata 321 for Timer 4 / 2 x Renata 377 for Timers 2 & 3

Pay attention when closing back plate to clean and lube seal and don't damage it. The watch may not be water resistant anymore

On top of .stl and .3mf files I uploaded Fusion 360 .f3d one so you can modify the design and adapt it to your needs. The Fusion 360 file includes also the opener for the Ice-Watch

As usual, feedback and comments (and for sure "likes") will be always welcome. Feel free to post nice pictures of your makes

Enjoy
