Using this mod part for: titanium sk007 case
Fastest watch parts shipment ever!

I have to say, I've ben modding watches for at least 10 years. 99% of the mod parts are out of Singapore, but to date, this shipment was the fastest by a long shot. So far everything looks good but I won't get to assemble for a few days. Thanks!
