Zenith Defy Extreme Diver Microblasted Titanium 43mm 97.9600.3620/21.I300, Although the main colors are still three, because its grade 5 titanium case is treated with a very textured dark gray micro-sandblasting, it will look relatively integrated when paired with a black ceramic bezel and a black dial, and will not look as sharp as the previous watch. The fluorescent yellow scale ring and hands are the only bright colors of the entire watch, which not only form a sharp contrast with the dark case bezel, but also become the finishing touch to brighten the entire watch.

Compared with other integrated luxury sports watches on the market, the biggest difference in the appearance of Defy Extreme is that while increasing the diameter of the watch, it uses a double-layer bezel that highlights the layers and a crown shoulder that symbolizes solidity and toughness. The latter two features are not only continued in the Defy Extreme diving watch, but also achieve a breakthrough in design on this basis. The Defy Extreme diving watch cleverly swaps the double-layer bezel on the Defy Extreme chronograph in an interesting way, putting the 12-sided bezel originally on the bottom of the chronograph on the top, and the circular bezel on the bottom becomes the single-rotating diving scale bezel that is essential for diving watches. This clever design technique not only pays tribute to the classic A3648, but also follows the design language of Extreme, and also allows the ceramic bezel to be better protected. Although many friends will find this double-layer bezel diving watch very strange when they first see it, this design is so reasonable on Zenith https://www.aomwatches.is.
In addition to the highly recognizable double-layer bezel, another good thing about this watch is that although it is an Extreme, it does not blindly seek large size for the sake of coolness, but chooses to be restrained. Its 42.5mm diameter is obviously suitable for more friends. Even though its 15.5mm thickness is indeed a bit thick, it is waterproof to a depth of 600 meters after all. In addition, its light weight of grade 5 titanium can greatly help you alleviate the discomfort caused by thickness. After trying on this watch, I felt that not only the weight ratio was reasonable, but it was so close to the wrist after matching the chain strap. Although the dial of this watch uses the iconic four-pointed star pattern of the Defy series, the four-pointed star on this dial is obviously larger to highlight its visual impact as an Extreme. Of course, if this watch can burn the ceramic bezel to the same fluorescent yellow as the scale ring, it will be perfect.
Although the waterproof depth of this diving watch reaches 600 meters, the famous El Primero movement of Genelec must also be seen. Through the sapphire case back, we can see that this watch uses the El Primero 3620 high-frequency automatic movement. This movement is the El Primero 3600 movement that can time one-tenth of a second without the chronograph mechanism. On the technical level, in addition to the El Primero movement’s iconic high swing frequency of 36,000 times per hour, with a silicon escapement wheel and pallet fork, it also has a power reserve of 60 hours.
