  • 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 3ATM, which means they can withstand pressures equivalent to a depth of 30 meters. 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!
  • How do I set my GMT?
    NOTICE: Read these instructions in whole. They will give you a good understanding of the operation of the Seiko Calibre NH34 (4R34) movement, and reduce any potential damage and failures in operational functionality. Warning: Do not operate the date or the GMT quick set from the crown between the hours of 9pm and 3am as you risk rendering the date change mechanism useless. If you don’t know the time, don’t change the date. More on this to follow. Manual Operation of the movement is controlled from the crown, some may call this a winder. The crown has three operating positions that control the different functions and complications of the Cal. NH34 (movement). Selecting the desired operating position is achieved by pulling the crown out gently. If you pull it too far, aiming to achieve the second position (date operation) you can simply push it back in and gently pull again. Hand-winding – Calibre NH34 (movement) The first operating position of the Calibre NH34 (movement) is the hand winding function. The first position is where your crown is at rest. This can vary depending on your watch’s design, there are two options. You have a sports watch where the crown screws closed to create the water tight seal. The first positions is found by unscrewing the crown until it is no longer engaged with the locking mechanism on the case. If your watch does not feature the screwed crown. The closed position (most pushed in) is the first operational position. The first operational position is where you can hand-wind your watch. Essentially, this is putting power into the reserve. Approximately forty hand-winds of the crown in a clockwise rotation in this position will supply the reserve with a full supply. This will last approximately forty-one hours if unworn. If you intend to wear your watch everyday, your watch will require no further winding as your movement will supply power through the autowinding mechanism. Date and GMT Quickset – Calibre NH34 (movement) The second operating position of the Calibre NH34 (movement) controls the quickset of the day date and GMT complication. Warning: Do not operate the date and GMT quick set from the crown between the hours of 9pm and 3am as you risk rendering the date mechanism useless. If you are unsure of the time your watch is displaying with regards to the 24-hour date function, skip to next, the third operational position, and follow instructions to change the time so you are sure to be outside this region of operation where your risk damage to your timepiece. Date: Changing the date is done by turning the crown anti-clockwise. You will see the date wheel complete a part rotation and the next number will drop into view. GMT: This movement has an additional hand (a fourth hand). This is a GMT hand and tracks the time in a second location. Changing the time of your desired second location is done by turning the crown clockwise. You will see the GMT hand complete a part rotation. Each click of the hand rotates the GMT hand one hour. This can be operated like so, until the desired second location time is selected. It will appear as half an hour on the dial as the GMT hand takes twenty-four hours to make one full rotation of the dial. The hour hand makes two full rotations in a twenty-four hour period. Setting the Time and Hacking – Calibre NH34 (movement) The third operating position of the Cal. NH34 (movement) allows the user to set the time and affect the second hand hacking (stopping) function. The third and final operating position can be reached by pulling the crown out to the final position. You will notice when are in this position, as the second hand will stop moving. This is the hacking feature of your Cal. NH34. The crown rotated in a clockwise position will move the hour and minute hands in a clockwise rotation. You should set the time by using the clockwise rotation for the bulk of the movement. It is understandable that you may miss the time that you wish to set your watch to. In this case, micro adjustments to the time in an anti-clockwise rotation are fine, but if you move over a few hours past, it is recommended that you continue the clockwise rotation until you achieve a full rotation. DON’T: Turn your crown anti-clockwise in the hope that the date will go backwards. It will not. You will not be happy with the results!
  • How do I use the chronograph function on my custom watch?
    To use the chronograph function on your custom watch, follow these steps: (see pic below) 1. **Start the Chronograph:** Press the top pusher (located at 2 o’clock) to begin timing an event. The seconds hand (usually centrally mounted on the dial) will start to sweep or tick. 2. **Stop the Chronograph:** Use the same top pusher to stop the chronograph when the event ends. This button is typically operated with the index or middle finger, with the watch case supported by the thumb. 3. **Read the Elapsed Time:** Chronograph watches display the time measured on the stopwatch separately from the current time of day. The format can differ depending on the design and movement inside, with some only counting up to 30 minutes while others can measure up to 12 hours. The seconds, minutes, and hours for the chronograph are usually read on separate subdials. For example, if your watch has a 30-minute counter/subdial at 3 o’clock and a running seconds hand at 9 o’clock, 15 minutes and 20 seconds will be shown on the sub-dial at 3 o’clock and the centrally mounted seconds hand, respectively. The seconds hand at 9 o’clock will continue to sweep, as it measures the time of day, not the time on the stopwatch. 4. **Reset the Chronograph:** The bottom pusher (around 4 o’clock) resets the chronograph to zero. Note that some variations, like the flyback chronograph, allow you to reset without first stopping it. A monopusher chronograph uses a single button for all functions—stop, start, and reset. A split-seconds or rattrapante chronograph allows you to measure two separate events simultaneously. **What Not to Do With a Chronograph:** Avoid pressing the reset button when the chronograph is running unless it’s a flyback chronograph. Leaving a chronograph running continuously is not strictly bad for the watch but will reduce its power reserve and put more wear on some components. If your chronograph watch is made for water activities, double-check with the manufacturer that the pushers can be safely operated underwater before doing so.
