Like on the original, you’ll find a solid back with a vintage Oris logo on the Divers Sixty-Five, which adds slimness. Inside beats the Oris 733, ancaliber based on the Sellita SW200 with 38 hours of power reserve at 4 Hz (28,000 bph).
While the watch is super-lumed all over, its depth rating is what is super-interesting. Notice that it’s only resistant to 100 meters. Like the original, this Sixty-Five acknowledges that most divers won’t ever find themselves anywhere near that depth. That’s not the easy way out, it’s the cool way out.
