In 2019 at the Baselworld the well-known and reputable brand of Seiko presented the LX series of Prospex timepieces. It introduced the series in the Air, Land and Sea category. The Prospex LX series features several watches that are equipped with the caliber movement of the Spring Drive.
The Seiko LX Prospex line shows upgrades in reference to the cases made of titanium, edges polished with Zaratsu and the already mentioned movement of Spring Drive. Today we are looking at the Seiko Prospex SNR031 model and dive watch and we are reviewing its features and performance in detail. The particular SNR031 is a sports male watch that will immediately appeal to you with its simple but yet powerful design.
Seiko Prospex SNR031 Features
With a diameter of 44.8mm, this case of Seiko Prospex SNR031 is said to be rather large. However, do not be fooled by the large dimensions and you can be certain that this timepiece lays comfortably on your hand wrist. The comfort is ensured by the case gravity center which is set rather low as well as the concept of the case design itself, in addition, completes the comfortable wrap of the watch around the hand wrist.
The length of the case is 50.9 mm and its thickness is 14.7 mm. The many angles are faceted, which forms the shape of the case which is polished with zaratsu. What this basically means is that this special technique enables the wearer to observe his/her reflection without distortion.
The case is made of titanium with sapphire crystal and black dial. This SNR031 has been tested and approved for up to 300m depth which makes it suitable for diving. Compared to other brands that use a valve for helium release, Seiko as with the other diving watches relies on the case structural integrity that prevents cracking of the crystal in case of decompression.
The simple elegance of the black dial makes this watch a perfect choice for almost anyone. The case has a super-hard coating with polished flat surfaces. The numerals and the markers which are engraved have a slightly noticeable blue infill that perfectly merges with the black, and thus emphasizes the simplicity but yet the elegant touch of the timepiece.
The dial has large hands that are luminous together with the markers that point the hours for better legibility regardless of the light conditions. Everything is made for easy operation of the watch even while diving so thus you have a huge bezel that is unidirectional. The bracelet strap is made of silicone and a clasp that is secured with a lock and it is three-fold. This watch is primarily intended for male watch lovers.
The Movement: Spring Drive Caliber 5R65
The caliber movements explored in Spring Drive understand great precision in time expression and a great degree of engineering design touches. 5R65 is a popular choice caliber for people who love adventure and are keen on sports. The caliver provides a precision of one-second per day together with high degree of shock-resistance as well as resistance to temperature.
Seiko LX Prospex SNR031: Summary
Generally speaking, this timepiece is a great watch for anyone’s hand and it is suitable for wearing day-to-day as well as specifically for diving. The Seiko Prospex LX is magnificently designed with a great look and an exceptional robustness.
The case made of titanium is sturdy and robust. The caliber movement and the Spring Drive are unique for Seiko providing smooth movement of the hands that move silently. The dial is extremely beautiful in patterns and it is very legible. It is a watch that operates smoothly with all the functioning duties underwater when swimming or scuba diving. As mentioned the case is made of titanium and it has a corresponding black silicone bracelet. Although the size of the watch is quite large, the Seiko Prospex SNR031 is an extraordinary model for sports daily wear. Seiko Marinemaster Prospex SNR031 Marinemaster
