Longines Master Collection's new model features a diameter of 40mm and for the first time incorporates the original Japanese Seiko NH36 movement. Its specific advantages are as follows: .1. The appearance details are closer to the original version, with a three-piece case design that enhances water resistance. Given the advantages of the movement, it can maintain the original synchronized dimensions of 40mm in diameter and 11.5mm in thickness, and it is equipped with a domed double anti-reflective sapphire crystal.2. It is equipped with the original imported Japanese Seiko NH35 movement, correcting the original L888.5 skeletonized automatic rotor. The color of the rotor is the same as that of the new 40mm model, filled with rose oil. The rotor breaks the bottleneck of the Citizen 8215's unidirectional oscillation, allowing for bidirectional movement, which is more flexible and quieter, thus providing superior performance in terms of power reserve functionality.3. The date window has been optimized to match the original size, with clear date font.4. The model number, warranty card number, and other identifiers are integrated into a three-code system for convenience.
