This interesting wristwatch from artistic watchmaker Mr. Jones reveals a colorful skull on the face whenever the hour and minute hands align, apparently inspired by Hans Holbein’s 1533 painting. Additional details include a PVD coated 316L stainless steel casing, a Ronda 513 quartz movement, a black leather strap with blue stitching and water-resistant at 5ATM. Limited to just 100 pieces, retails for £145 GBP (approximately $234 USD).
