FREQUENTLY ASKED QUESTIONS
A Seiko mod is a one-of-a-kind timepiece, custom-made and impossible to find in traditional retail stores.
Handcrafted by experts, these watches combine original Seiko components with carefully selected non-Seiko parts, chosen for their quality and style.
Please note that these are not official Seiko products. Our company is entirely independent and has no affiliation with Seiko or any other brand.
We use NH35, NH70, and NH72 automatic mechanical movements for our modified Seiko watches. These movements, manufactured by Seiko, are renowned for their reliability and accuracy, providing an exceptional watchmaking experience for our customers. Each of these movements is carefully selected to ensure long-lasting performance and outstanding quality, adding invaluable value to our modified Seiko watches.
Each watch undergoes a series of rigorous tests to ensure its performance and reliability:
- Water Resistance: A thorough check of the water resistance to ensure perfect sealing.
- Demagnetization: A demagnetization process to preserve the proper functioning of sensitive components.
- Chronometer Adjustment: Precise adjustment of the watch to achieve accuracy within -5 to +5 seconds per day.
These quality checks are carried out with care before shipping, ensuring you receive a watch that is ready to use, reliable, and high-performing.
For every order, we provide you with the necessary tool to adjust the bracelet to your wrist yourself.
This allows you to easily customize the fit at home, at no extra cost.
