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.
