The design of the Promaster Mechanical Diver 200m Fujitsubo is nothing really spectacular, as it shows the typical design elements of classical dive watches. That very watch served as the inspiration for this modern-day titanium diver. Covered in barnacles, the watch miraculously was in running condition! The mechanical movement had survived years of being in water and dirt, protected by its case. And it comes with a fascinating backstory!īack in 1983, a Citizen Challenge Diver from 1977 was recovered from an Australian beach. One of the latest watches with this proprietary material is Citizen we have before us today. This combines the brand’s titanium processing technology, with the Duratect treatment. The culmination of Citizen’s expertise with this material is something called Super Titanium. By the year 2000, Citizen developed the Duratect surface hardening treatment, making titanium far less prone to scratches. Ever since Citizen’s first experiments, the company has perfected the process of machining titanium. Thus, it makes an ideal material for watches for multiple reasons. And above all, it’s much lighter than conventional stainless steel.

Titanium has the unique property of being resistant to rust, hypoallergenic and extremely strong. Although available in very limited quantities, Citizen’s X-8 Chronometer from 1970 paved the way for many others to come. Surprisingly, it’s Citizen that pioneered the first commercially-available titanium wristwatch. Most might consider Titanium to be a very modern material, but it has been used in watchmaking for over half a century. And we tell you all about this cool 1970s-inspired diver. Today, we take the Citizen Promaster Mechanical Diver 200m NB6021-17E, also known as the Fujitsubo, for a spin, with our latest video review. Citizen is surely known for its accessible watches with superb quality/price ratio, and the brand’s latest creation in the field of dive watches isn’t going to change this, at all. And a watch with a rather cool backstory too. Lightweight, extremely comfortable, good-looking, and a genuine performance bargain.
