Precision and Durability: The 2023 new Oyster Perpetual series M277200-31mm features a one-piece middle case, a screw-down case back, and a winding crown. The screw-down structure includes a double-lock system for enhanced waterproofing, securely fastening to the case for improved water resistance. It is equipped with a sapphire crystal that is scratch-resistant. Each hue of the dial is individually adjusted to achieve zero color difference, with polished hour markers, top-tier Swiss super bright ice blue luminescence, and a finely detailed texture with matching colors. Paired with an imported movement, its performance is particularly outstanding, ensuring precision and durability for a steady and reliable experience.
