11.7 mm is the headline
By Kenji Watanabe, Osaka ยท
For years I have complained about 13 mm Seiko divers, so I should be gracious when Seiko listens. The SPB453 is 40 mm by 11.7 mm, and with 300 m water resistance that is remarkable for the price.
It also brings the 6R55 with 72 hours of reserve, a slight improvement over the 6R35's 70, plus sapphire, solid back, black dial, date and rotating bezel on a steel bracelet.
I like the size very much. It would slide under a shirt cuff, which most Seiko divers cannot. My only doubt is that the design is so clean it can look a little plain next to the textured 62MAS dials. Some people will find that a virtue.
At 1,250 to 1,300 dollars, this is the Seiko diver I would buy today.
