I’ve had this watch for 25 years and all it needs from me is a battery every 4/5 years and the date and times changes due to calendar and BST/GMT changes. It never misses a beat. Yes it’s been through the wars but it’s been my diver watch in many seas and oceans over a number of continents and over a couple of decades. Now it’s a desk diver from time to time, but it always grabs people’s attention. In watch boutiques an AD will want to spend as much time taking about it as the time they spend talking about what I’m interested in. It’s never going to leave me and I it!
