Originally posted in November of last year, the video already has more than 1.75M views and, once I clicked play, I could not stop watching. Presented with a jazzy soundtrack and without any voice-over, Australian watchmaker Nicholas Hacko opens up a severely water-damaged Rolex GMT-Master II and proceeds to slowly tear the watch down to its cruddy component parts, clean it all up, and then put it back together again. Like a sort of visual ASMR, I found the video to be riveting and very calming as it mixes the fun of seeing a specialized skill set put to work with the shock of just how much damage the water did to the various parts of the movement.
