Tudor 395

The Tudor 395 represents an automatic mechanical movement engineered by the Swiss watchmaker Tudor. This caliber is designed to provide reliable timekeeping through its self-winding mechanism, which harnesses the natural motion of the wearer's wrist to power the watch. Measuring 26 mm in diameter and 5.95 mm in height, the Tudor 395 is a movement of moderate dimensions. Its diameter allows for integration into a range of watch case sizes, from more compact models to those with a broader presence on the wrist. The height contributes to a watch that maintains a reasonable profile, avoiding excessive thickness and enhancing wearability. Within its construction, the movement incorporates 17 jewels. These synthetic rubies are strategically placed at points of high friction, primarily where pivots rotate. Their purpose is to reduce wear on metal components, thereby contributing to the movement's longevity and consistent accuracy over time. In terms of performance, the Tudor 395 operates at a frequency of 21,600 vibrations per hour (vph), which translates to 3 Hz. This beat rate means the balance wheel completes 3 full oscillations per second, or 6 half-oscillations (beats), resulting in a smooth, albeit not ultra-high-frequency, sweep of the seconds hand. A movement operating at this frequency is often associated with robust reliability and potentially longer service intervals due to less rapid wear on components compared to higher-frequency calibers. The power reserve for the Tudor 395 is 46 hours. This duration indicates that a fully wound watch can continue to operate for nearly two full days when not being worn. For the wearer, this means the watch can be removed for a night or even a full day and still be running when picked up again, though it would require winding or wearing if left unworn for much longer than this period. A technical specification, the lift angle of the balance wheel is 52°. This measurement is primarily relevant for watchmakers, as it is a critical parameter for accurately calibrating and regulating the movement using electronic timing machines. Collectively, the specifications of the Tudor 395 describe a functional and robust automatic movement. Its self-winding nature eliminates the need for daily manual winding, offering convenience to the wearer. The moderate dimensions ensure versatility in watch design, while the 17 jewels contribute to its durability. The 46-hour power reserve provides practical autonomy for daily use, and the 21,600 vph frequency delivers consistent timekeeping. The Tudor 395 is thus characterized by its practical design, aimed at delivering reliable and enduring performance for its users.
