Hello,

Im planning to purchase this cosmic, however the backcase is very different from what ive seen on other cosmics.
Im wondering if someone can help me with this, is this not an original backcase?
Seller has given me this info:
Ref. number: 166.026 and piece number: 25337635

 

sharing my cosmic.

 

Thank you!
Your back case look exactly like the ones ive seen. Smaller dont.
Nice watch!

 

thanks. it's a single solid case or monocoque for 100% water proofing design.

 

looks ok to me.
