A diver's watch equipped with a new in-house mechanical movement

HosodaThe Promaster is Citizen's professional watch. The collection is divided into three categories: Marine, Land, and Sky. This time, we will review the new Mechanical Diver 200m model equipped with the automatic movement Cal. 9051.

(I.e.This is a diver's watch, so it has excellent visibility, and above all, the design is cool.

The bold indexes and hour and minute hands ensure good visibility, while the pyramid-shaped embossing on the dial and bezel and the screw design give it a tough look.

DoiI was also very impressed at first glance. The bezel has a completely new design. The sides and numbers are three-dimensional, with an elaborate finish.

(I.e.It's well made. It's made of titanium and is light, so you can wear it around town.

HosodaIt's 15.3mm thick, but surprisingly light.

(I.e.Yes. The thickness is unavoidable, but the weight didn't bother me at all.

DoiOne negative point is that the numbers on the bezel are a little hard to read, as they are three-dimensional but not colored.

HosodaThat's right. The luminous markers allow you to see the starting point, but can you read the numbers clearly underwater? When diving, you'll also be wearing gloves, so you won't be able to trace the numbers.

Promaster Mechanical Diver 200m Bezel

The bezel counter is not colored, but it has a three-dimensional appearance. The sides are also notched to allow for easy operation with gloved hands. The operation is smooth.

(I.e.The three-dimensional effect is less apparent underwater than on land, so there is certainly room for improvement in the bezel display. However, since colors are also less discernible underwater, perhaps they chose not to add color.

HosodaIt would probably be easier to read if the numbers were coated with luminescent paint, but maybe they'll actually be readable if I go underwater, so I'll go underwater next time and check (lol).


The urethane strap is also ingenious

HosodaBy the way, where did you all wear it? The case is thick, but I guess you just wear it on your cuff or over your sleeve.

DoiI wore it during the lingering heat of summer, so I wore it directly over short sleeves.

(I.e.I also wore it normally.

HosodaI tried wearing it while climbing a mountain, and it was convenient to wear over long sleeves. It's shock-resistant in case something happens, and the unidirectional rotating bezel was useful for measuring how many minutes I'd climbed from the rest stop. It's the exact opposite of its intended use, but it was a great mountain climbing watch (lol).

Dive Watch Straps

The urethane strap has a thicker tip to prevent the watch from falling, and is embossed in the same way as the bezel and dial.

(I.e.Its specs as a diver are serious, but it's also well-balanced for everyday use as a hill diver.

HosodaHowever, there was one thing that bothered me about the strap. The end of the strap is thick for safety, but when I tried to wrap it over my sleeve, it was quite difficult because the length was just right. I think it's good in the sense that it won't come off once you put it on, though.

Case Side Diving Watch

The lug-integrated middle case holds about half of the bezel. In addition to the strap that comes with the watch, a long strap for diving is also included.

(I.e.I think it would be easier to put on if the strap had more bellows and was more stretchy. Oh, but it seems like an extension strap is included. It would probably be better to change to this when wearing it over a wetsuit.
