Orient's best diver, I think
By Kenji Watanabe, Osaka ยท
The M45 Diver 1964 takes its inspiration from a 1964 Orient diver, and the reissue does a good job of keeping the old shape while adding modern hardware.
41 mm by 13.7 mm, steel, sapphire, 200 m, F6N47 automatic with 50 hours of reserve, date, power reserve indicator, rotating bezel. That is a well-equipped watch for 780 to 900 dollars.
The power reserve indicator on a dive watch is unusual. Some people dislike it. I do not mind, though I would prefer it smaller.
Against the Seiko 62MAS reissue at about 1,200, the M45 is cheaper and has the extra indicator, while the Seiko has the stronger history and the 70-hour 6R35. I would choose the Seiko for heritage, the Orient for value.
