Other: It's no secret that the yachting regatta countdown is one of our all-time favorite complications here at watchsteez.com. If you haven't been out yachting recently, we'll break it down for you: The white, blue, and red segments each represent 5-minute intervals within the 15-minute countdown. In the 15 minutes leading up to a race, yachts are jockeying for position behind a starting buoy - The tri-color coding makes the chronograph easy for skippers to read at a glance, letting them know when they can cross the starting line. Given the relative obscurity of the sport, tool watches designed specifically for this purpose are all the more rare. We absolutely love this OW with its incredible dial with big-eye regatta register and large case with stainless steel bezel. Furthermore, this is the best example that we've ever had the privilege of offering!
