cal. 9051. Derived from the Miyota cal. 9015 the cal. 9051 that has 42-hour power reserve and runs within -10 to +20 seconds a day.
Functions
  • ・Magnetic-resistant mechanical movement Cal.9051
  • ・ISO compliant water resistance to 200 meters
  • ・Up to 42 hours of running time when fully wound
  • ・Daily accuracy of -10 to +20 seconds
Anti-magnetism is crucial in a mechanical watch. Labelled as a proper professional instrument, the Citizen Promaster Mechanical Diver 200m is developed with that in mind. The calibre 9051 movement can continue to perform in circumstances with magnetic fields up to 16.000 a/m (amperes per meters), which equates to about 200 Gauss. To put this into perspective, an average mechanical ETA calibre is anti-magnetic up to 4,800 a/m. There are watches with higher anti-magnetic properties on the market – think about Omega and its 15,000-gauss technology – but this will get you a very long way and should do perfectly fine, even onboard ships with magnetic compasses.

On this episode we take another look at an excellent new watch from Citizen, this NB6004-83E has the goods but is it enough to take on comparable Seiko Prospex offerings?

  • ※1 Super Titanium™ is CITIZEN’s proprietary surface hardening technology to treat solid titanium. It is at least 5 times harder than stainless steel, resistant to scratches, lightweight and gentle to the skin for comfortable wearing.
  • ※2 ISO: International Organization for Standardization. “ISO 6425 diver’s watch” for all diver’s watches to ensure diver safety.
  • ※3 Duratect is CITIZEN’s proprietary surface hardening technology that enhances the surface hardness of metals such as stainless steel and titanium, protecting watch bodies from scratches and damage. This technology offers excellent abrasion quality and maintains the luster of metals for long periods of time. Duratect DLC achieves Vickers hardness of 1,000-1,400 by creating an amorphous carbon hard film—mainly composed of carbon and hydrogen—on the surface of the material. Duratect MRK and Duratect MRK Gold achieves Vickers hardness of 1,300-1,500 Hv by instilling gas onto the surfaces of titanium materials to harden.
