Citizen Mechanical collection Automatic Promaster 'Fujitsubo' Marine Diver NB6021-17E. This watch has a case width of 41mm, thickness of 12.3mm and lug width of 20mm and uses Sapphire Crystal.

In a modern interpretation of the original 70’s dive watch, Citizen re-introduces the new Promaster Mechanical Diver NB6021-17E – the timepiece with a deep backstory. Inspired by the design of the 1977 Citizen Challenge Diver that was found on an Australian beach in 1983, the watch was covered in barnacles after having been submerged in the Pacific Ocean for years......and was still ticking! That history has inspired the new Promaster Mechanical Diver and given it the affectionate nickname, Fujitsubo – Japanese for barnacle.

The lightweight and scratch-resistant Super TitaniumTM case of the Promaster NB6021-17E is complemented by a black dial with embossed hands and a classic green luminous treatment for a vintage feel, a rotating elapsed-time bezel, and an anti-reflective sapphire crystal. The retro look is completed with the black polyurethane strap with a raised square pattern.

This advanced timepiece with automatic movement features enhanced magnetic resistance to protect against external magnetic fields, as well as a 42-hour power reserve. This high-performance watch is ISO compliant and water resistant to 200 meters. Caliber number 9051.

The new Cal. 9051 movement uses anti-magnetic materials for the balance spring and surrounding components to boost the overall magnetic resistance of the watch. This new model is capable of maintaining performance even when placed 1 centimeter from a device emitting a magnetic field of 16,000 A/ｍ. The watch is also resistant to magnetic fields from everyday devices, including smartphones, and it can even be used aboard ships with magnetic compasses. In addition to magnetic resistance, the watch also has ISO compliant*2 water resistance up to 200 meters. It can run for 42 hours when fully wound, with daily accuracy of -10 to +20 seconds – solid performance for a mechanical watch. The hour hand, minute hand, and indexes have a luminescent coating to ensure high visibility.

What we Love: This is the complete dive watch and one for the collectors.
