SUGESS Men's Analogue Moon Phase Chronograph Watch with Panda Dial, Luxury Leather Strap, and See-Through Back, 40mm (ST1908MGJ)

1. The strap is made of genuine leather, which is a major benefit: it's lightweight. (Band material/type: genuine leather. We chose faux leather because entering genuine leather would result in an error.) 2. The case back is see-through, allowing you to enjoy the movement, which is one of its charms. 3. The crystal is made of sapphire glass with anti-reflective coating on both sides, ensuring excellent visibility. 4. The moon phase is one of the most difficult functions to achieve, even among mechanical watches, as it requires precision. 5. The warranty period is one year from the date of delivery of the product. If a malfunction occurs within the warranty period due to our fault, we will repair it free of charge.
