Benefits & Use Cases

This watch excels in formal and business environments, where its refined design and mechanical complexity convey professionalism and taste. It pairs seamlessly with suits, dress shirts, and blazers, making it suitable for weddings, corporate meetings, dinner parties, and other elegant occasions. The moon phase feature adds a layer of sophistication appreciated by watch connoisseurs, while the automatic movement ensures practical, battery-free timekeeping. For casual wear, the brown leather band and tonneau case offer a stylish accent that elevates everyday outfits without appearing overly ornate. As a self-winding watch, it performs best when worn regularly, harnessing natural motion to maintain power. Those with active daytime routines will find it keeps accurate time with minimal intervention.

Important Notes

Due to its mechanical nature, the watch requires daily attention to maintain operation. The power reserve lasts approximately 24 hours, meaning it will stop if left unworn overnight. To resume function, manually wind the crown 15–20 times in a clockwise direction until slight resistance is felt—do not overwind, as this may damage the movement. After winding, gently shake the watch to initiate motion. Time setting is done by pulling the crown to the outer position, adjusting the hands, and pushing it back in. Each unit undergoes thorough quality inspection before shipping and arrives with the official SEWOR branding and protective packaging. Please note that warranty details are available through the manufacturer’s support portal. This model is not discontinued and remains in active production.
