First of all, the case size is 40.9*12.3mm which is almost as the same the per original, not only because it is made out from a 1:1 case but also because the team conquer so many difficulties to develop a replica A79350 movement. Some editions are not able to do the same size case as original edition is because it is limited by the movement inside of it, some factories are not able to copy the original movement. Then let’s move to the dial, the craftsmanship and fine details are just the same as original. IWC’s logo is very clear, and the character size is the same as original, there is no difference by looking at it. The outside markers for chronograph second function is also copied greatly. The blue long needle is for showing chronograph second, and sub-dial at 12:00 position shows chronograph minute. Sub-dial at 6:00 position together with two hands in the middle to show the time. Time Markers are numeral. Look into carefully, even the axis to hold those three hands are done as well as per original, perfectly in details! Both V6 edition and original’s front glass are made of sapphire crystal, this is a easy job for ZF to follow. Look at the case side, no matter the polish or matt work, they are exactly the same as the genuine. On the crown and the buttons for adjust functions, they are looking the same in shape and engraving logo on it, but V6 edition’s is painted with blue coating which is for protecting them from the scratch. For the strap, the original one is using crocodile leather, V6 edition’s standard strap is real cow leather but Z factory also offer crocodile leather with extra pay.
Titanium is the material of choice for the inner caseback on the Deepsea due to its strong corrosion-resistant properties and its ability to repeatedly flex under stress without developing the same degree of metal fatigue as steel. Since the crystal on the Deepsea will be subjected to the same extreme pressures as the caseback, its scratch-resistant sapphire crystal has been beefed up to be a massive 5.5mm thick, and it is crafted in a domed shape (without a Cyclops magnification lens) to better distribute the pressures being exerted on the face of the watch.Like both the Submariner and the normal Sea-Dweller, the Deepsea is equipped with Rolex’s Triplock winding crown that screws down and uses a system of gaskets to create three sealed zones to protect against moisture intrusion. Additionally, since the Deepsea is a variation of Rolex’s Sea-Dweller collection, its case is equipped with a helium gas escape valve, which allows the watch to safely be used for saturation diving applications.One of the hallmark characteristics of modern dive watches is the degree of the over-engineering present in their designs and the almost-ludicrously excessive performance-statistics that manufacturers are able to achieve. Although the Rolex Deepsea Sea-Dweller is easily the most capable and robust dive watch available in Rolex’s current catalog, only a very slim percentage of its owners will ever require even a small fraction of its incredible underwater functionality. Regardless, the Ringlock system and the case of the Deepsea are the perfect embodiment of form following function, as the watch was specifically designed from the ground-up to be the ultimate deep-sea diving timepiece.
The earliest movement used in the Rolex Explorer II was the Caliber 1575, but over the years it was replaced with more technically advanced movements to help this watch reach its full adventure potential. The first big upgrade was the Cal. 3085 which allowed the 24-hour hand to be adjusted independently from the 12-hour hand. This meant the Explorer II no longer just indicated day and night hours, but could also be used to track a second time zone – turning it into a GMT watch. Then came the Cal. 3185 which was improved upon more with a Glucydur balance wheel that is not only paramagnetic but was resilient in extreme temperatures. The 3186 came next with a blue Parachrom hairspring that is anti-magnetic and shock resistant for even better durability. Finally, we have the modern-day Cal. 3187 which features all the upgrades this watch has gained over the years – from the GMT functionality to the blue Parachrom hairspring. It’s also notable for its high-performance Paraflex shock absorbers, 31 jewels, -2/+2 seconds per day accuracy and 48-hour power reserve.The Submariner has a much longer history, so we’re going to start with the automatic Caliber 3135, which, while upgraded over the years, has been used in all date-displaying Submariner watches since 1988. While the aesthetics of the Submariner can vary, the Cal. 3135 has remained a trusted source of power for this beloved timepiece because of its sheer reliability. Today, the upgraded Cal. 3135 movement is COSC certified, outfitted with the anti-magnetic and ultra shock-resistant blue Parachrom hairspring, and boasts an impressive 48-hour power reserve just like the Explorer II.
