Delma, a Swiss watch brand born in the late 1920s, gained recognition for its high-quality diving watches in the 1960s. Iconic models like the Periscope from 1969 and the professional diver’s Shell Star of 1975 laid the foundation for the extensive range of Diver references across six distinct product lines that Delma offers today. Since 2011, the Blue Shark series has continued this tradition, delivering rugged and stylish timepieces tailored for underwater exploration and water sports enthusiasts. These watches prioritize durability and functionality and come at a fair price. The latest addition, the Blue Shark IV, not only upholds this legacy but pushes the envelope regarding water resistance.
The Delma Blue Shark I set a high standard with its remarkable water resistance of 3,000 meters, serving as the cornerstone for subsequent releases like the Blue Shark II (2016) with an updated bezel and the same 3000m capability, and the Blue Shark III (4000m) in 2019. The Blue Shark watches share core attributes, including stainless steel cases built to withstand the demands of underwater adventures, unidirectional rotating bezels, crown protection, luminous markers, prominent hands for underwater readability, a date display at 3 o’clock, and a choice of orange, black, or blue dials. Wearers can perform easy strap/bracelet operations to wear these diver’s instruments on a metal bracelet or a rubber strap, ensuring comfort and versatility. However, the Blue Shark III introduced a new depth rating and user-centric improvements, such as convex crown protectors and new security screws with custom tools for easy and reliable bracelet and clasp adjustments.
The latest addition to the series, the Blue Shark IV, takes the plunge to even greater depths, reaching a staggering 5,000 meters below the surface. Its stainless steel case measures 47mm in diameter and 20mm in thickness, slightly larger than its predecessor. The unidirectional stainless steel bezel offers an excellent grip and features bright orange markings. You’ll find the helium escape valve on the left side of the case. Turn the watch over, and you’ll encounter the domed solid caseback adorned with laser engravings, including an imposing shark image, mention of the impressive 5,000m depth rating, and other essential details about the watch.
The dial design carries forward from the previous model, offering signature choices of blue, black, or orange colours, and there’s also an option for a black DLC-coated bezel. This variety results in six distinct-looking references in the Blue Shark IV collection, catering to diverse tastes and preferences. Delma’s commitment to functionality and legibility is evident, with indices and long and wide hour and minute hands, with orange and green Super-LumiNova ensuring that the Blue Shark III and IV remain easily readable even in the most challenging underwater conditions.
Delma has chosen the reliable Sellita SW200-1 movement to power the Blue Shark IV, a departure from the previous ETA 2824-2 movement used in the earlier version. While both automatic calibres offer similar characteristics, including a 38-hour power reserve and a frequency of 28,800 vibrations per hour, Sellita movements are more readily available, a factor that brands like Delma appreciate. When you’re 5,000m deep underwater, you want a watch equipped with a time-tested movement, and the SW200 fits the bill perfectly.
The fourth generation of the Blue Shark is available with the signature solid steel three-row bracelet. The watch’s presentation box includes a rubber strap adorned with an embossed Delma logo along with special tools for dealing with safety screws, making it easy to switch between the bracelet and the strap. Delma plans to produce the Blue Shark IV in limited quantities, with 999 pieces available per case type. The pricing for this exceptional timepiece is set at EUR 2,390; if you opt for the DLC-coated bezel variant, it’s EUR 2,490.
