Eterna Royal KonTiki GMT Automatic Watch

From the oversized crown and industrial-looking lugs to the five studs around the case, the Eterna Royal KonTiki has a bank vault–style look to it. Capable of tracking two time zones and the date, this 42-millimeter automatic is highly functional, too. What’s more, it’s fueled by Eterna’s own 30-jewel movement, boasting a sizeable 65-hour power reserve. That means you can let it sit for a couple days and come right back to it without rewinding. Materials wise, the Royal KonTiki comes backed by a stainless steel case and sapphire crystal. It’s water resistant to 100 meters, to boot.
