  • How are these watches made?
    These watches are constructed using Seiko NH-style movements and are meticulously handcrafted by me from individual components sourced through a reliable supply chain. Each timepiece is manufactured in my workshop, where I personally oversee the quality control process to ensure the highest standards are met. I use only sapphire crystals and 904L and 316L steel for cases.
  • How long does it take to build and ship my watch?
    Each watch is expertly custom-built and generally requires a completion time of 2 to 3 weeks. Upon finalization, I will dispatch your watch via an express service, and you will receive a tracking number to monitor the shipment at every stage. This approach ensures swift and secure delivery directly to your doorstep.
  • Are these watches waterproof?
    My watches are rated to 5ATM, which means they can withstand pressures equivalent to a depth of 50 meters (approximately 164 feet). This rating makes them suitable for everyday activities such as hand washing, light rain, and splashes of water. However, I advise against using them for intense swimming or exposing them to hot water, as this may compromise the seals. While they can handle some moisture, avoiding full immersion will help maintain their appearance and ensure optimal performance.
  • Are these covered by a warranty?
    Certainly! Here’s a more detailed overview of my watch warranty and service commitment: Warranty Coverage: Each watch comes with a comprehensive one-year warranty that safeguards against any defects in movement or craftsmanship. This warranty ensures that you can enjoy your timepiece with confidence, knowing that I stand behind the quality of my work. Repair and Replacement: In the event that you experience any issues with your watch during the warranty period, I will promptly take care of repairs or provide a replacement at no cost to you. My goal is to ensure that you are completely satisfied with your purchase and that your watch remains in excellent condition. Post-Warranty Support: Even after the one-year warranty has expired, I am dedicated to supporting my customers. Should you encounter any problems—regardless of size—I encourage you to reach out. I am here to assist you with repairs, maintenance, or any inquiries you may have. Your satisfaction remains my priority, and I will strive to resolve any issues to the best of my ability. Commitment to Quality: I take pride in the craftsmanship and quality of my watches. Each timepiece is designed not only to be stylish and functional but also to stand the test of time. Your happiness with your watch is paramount, and I continually seek to uphold the highest standards in my work. If you have any additional questions or need further assistance, please feel free to ask!
