VSF Seamaster 300M 8800 Review & Details
This episode focuses on a detailed breakdown of the VS Factory Seamaster 300M diver watch (equipped with the 8800 integrated movement), covering authentication details, exterior characteristics, and functional operations.
Packaging and Accessories Identification
The VS Factory Seamaster 300 features specific packaging identifiers, including a product identification card and a long travel strap. For the steel bracelet version, an additional rubber strap is included. These accessories serve as key initial indicators for version verification.
Case Dimensions and Material Details
The watch features a unidirectional rotating ceramic bezel. The case diameter is 42mm with a thickness of 13.4mm, closely matching genuine specifications. The lume is dual-colored: the “lume pip” and hands glow green, while the remaining indices emit an ice-blue tone.
Crown Feel and Operating Logic
After unscrewing the crown, the winding feel is smooth and refined, noticeably different from the heavier resistance of the 2824 movement. The helium escape valve is screw-down functional. For time setting, pull the crown to the final position and adjust counterclockwise (referred to as “reverse time setting”). Date adjustment follows the same forward-reversing logic.
Date Jump Mechanism and Maintenance Advice
The movement features an instantaneous date change mechanism. The demonstration shows the date jumping precisely around 12:03, with no pre-jump behavior. It is recommended to avoid adjusting the date when the hour hand is positioned between 9 o’clock and 3 o’clock. Instead, move the hands to the lower half of the dial before adjustment to protect the movement gears.
Power Reserve Performance
The 8800 integrated movement provides an approximate 55-hour power reserve under laboratory conditions, demonstrating stable automatic winding efficiency and energy storage capability.
Movement Inspection Characteristics
The exhibition caseback is the key authentication point. During winding, the gear train operates clearly and visibly. The balance wheel features a black-disc design. Compared with the 2824-based versions, the central structure of the 8800 integrated movement is more open with no unnecessary obstructions. The movement bridge is engraved with VS Factory codes (e.g., 83669886), which can be used as a reference for identification.
Clasp and Bracelet Compatibility
Equipped with an extension clasp for easy adjustment. When set to the smallest configuration, the bracelet supports a maximum wrist circumference of approximately 20cm, suitable for most wearers.
