Blancpain is the first manufacturer in the world to launch mechanical diving watches. Today we will share the world’s top performance mechanical diving watches Blancpain X Fathoms, product number: Blancpain Sports 50噚 Series 5018-1230-64 watch. This watch reinvents and absorbs the features of Blancpain’s classic 1953 diving watch, combining it with a mechanical depth gauge to create an ultra-high-performance mechanical diving watch like never before.
Since the introduction of the first mechanical diving watch by Blancpain in 1953, the diving watch is no longer a novelty model. The X Fachoms watch is the latest model of Blancpain’s Fifty Fathoms diving watch series. The name of X stands for innovation and invention. The dial of this watch is more complicated, please browse the dial explanation as shown below:
Next, let’s watch an official Blancpain video to get a rough idea of the many aspects of Blancpain X Fathoms that have become “the world’s first” innovations.
The satin-finished titanium case has a diameter of 55.65 mm and a water-resistant depth of 300 meters. In addition, the watch is also equipped with a helium pressure relief valve for decompression during diving, and uses the classic unidirectional rotating bezel design of the Fifty Fathoms series for nearly 60 years.
The center of the dial is equipped with a depth-detection hand, with matte black as the background color, to enhance the contrast; the buttons at the 10 o’clock to 11 o’clock position of the case are used to measure the 5-minute countdown timer of the decompression time; and the 8 o’clock position is equipped with The button of the protection bridge is used to reset the dive depth record; the crown is at 3 o’clock.
Decompression decompression stop: Due to the influence of diving pressure, divers are required to stop in stages to rise to the water to adapt to the pressure. X Fathoms is also the first to be equipped with a 5-minute countdown timer, which is used for decompression stops on the dive, and is displayed on the dial at 10 to 11 o’clock.
There is a 1-15m depth indicator between the 12 and 9 o’clock on the dial’s outer ring. The 0-15m mechanical depth sounder, which operates alone, has an error of only +/- 30cm above 15m water depth.
As the world’s first mechanical sounding watch, its maximum depth can reach 90 meters, and it can record the depth of dive; the inner circle of the dial is a depth indicator of 0-90 meters, where the yellow arrow pointer is used to display the current depth, and the red pointer is used To indicate the deepest depth record.
The surrounding honeycomb grid is the watch pressure reducing valve mechanism: three honeycomb water inlets are used at the bottom of the case to direct water into the watch depth gauge to measure depth. The unidirectional rotating bezel still appears on the X Fathoms as a signature part of the diving watch.
The watch is also equipped with a delicate and complicated molded rubber strap: this strap has 14 movable joints, which can perfectly fit the wrist and ensure that in any environment, water can reach the sounding through the underside of the watch Gauge pressure film to ensure the accuracy of depth measurement.
Fluorescent paint is a compound with strong color sense. It absorbs light energy and emits bright color fluorescence under sunlight. The three-color fluorescent coating can fully ensure the readability of the pointer under water.
What’s more worth mentioning is the depth sounder film material that Blancpain dominates for this wrist. Its thickness is only half that of the iron film and the accuracy is relatively high. However, due to the non-linear deformation of the sounder film material alloy Features can not be avoided, Blancpain’s original solution is to solve the effects of this non-linear characteristic through a set of asymmetric gear mechanism.
The watch is equipped with a self-winding caliber 9918B. Its basic movement is Calibre 1315, which is originally produced by Blancpain. It has been used on a variety of fifty-inch models and has undergone severe tests. This movement consists of 385 parts, has 44 jewel bearings, is 13mm thick and 36mm in diameter. The use of anti-magnetic silicon hairspring, built-in 3 barrels, can ensure a power reserve of 5 days, unfortunately I can not find the movement picture of this watch.
