Howdy! Here's a custom hand aged MilSub date that I built. 20mm drilled lugs 39.5mm case, 48mm lug to lug, 16mm thick with domed acrylic crystal and 12mm without it. (It wears very well, don't be scared of the crystal height!) Regulated to the best of my ability NH35 movement. (I use the phone timegrapher app) All gaskets are lubricated and seated properly. I've worn the same case every day for a week in the ocean and pool with no issues! I build these with a lot of love and care! Thanks for looking! Asking 225$ Paypal, Shipped CONUS.
