The chronograph watch has a chrome steel case in matte finish. Power comes from Citizen’s in-house produced Calibre 9051, which we’ve already seen in the Promaster Mechanical Diver 200M NB6004 and the Series Mechanical NB6010 and NB6012. This automatic motion runs at a frequency of 28,800vph and makes use of 24 jewels.
As soon because the battery is fully charged, the second hand resumes regular operation. The authentic bracelet strap sadly is very tough on the wrist. As for the NATO, I had them once they first come out, as I was really serving in NATO with the Brits. I would much somewhat swap straps and bands on a watch than continuously reset the time – its often known as one of many things that finally causes serous injury and lack of use.

In 1983, a Citizen Challenge Diver from 1977 was recovered from an Australian seashore. The watch was covered in barnacles, indicating it had been underwater for quite a quantity of years, as these slowly construct up over time. Surprisingly, it was still in working condition as the motion was shielded from water and dust by its case. This fascinating little story serves as inspiration for Citizen’s newest dive watch, the Promaster Mechanical Diver 200M NB6021, which comes with trendy tech and supplies. A urethane strap is standard, which gets a design that blocks out on the lug, following a pattern we’ve seen fairly a bit lately, and I should say it works wonders here.
When I’ve received different issues on my mind, I’m not checking to see if it’s a wound, or if it’s lost or gained time. As far as I’m involved, Citizen’s Eco-Drive quartz movement was as massive an innovation because the Seiko Spring Drive, and definitely, it has far more market penetration. There are millions of them on the citizen promaster diver market, giving their house owners one less factor to fret about. Leave it on a windowsill for a day, and it’ll go for six months, whether or not or not you see the sun. It’s the best-performing solar movement I’ve seen when it comes to reliability, and the one thing you’ll should concern your self with is a date change at month’s finish.
