I messed up...

So in short I have a modded Pro Diver that I've turned into a vintage sub... I was trying to put the old movement in a different case, put the wrong crown stem in and did some nasty work to the old NH35. THANKFUL Adriel is a legend and stocks great movements. So I was able to pick up a new NH35 but the black date wheel version which is much nicer. My old movement is now in bits as I love learning how these things work, given its broken I figured now was a great time to crack it open. 10/10 on both the product and service as always. Cheers Adriel!
