Key Features
- Watch and Bracelet – 316L Stainless Steel
A high-grade corrosion-resistant steel widely used in professional dive watches. Known for its durability, strength, and excellent resistance to seawater and everyday wear. - Sapphire Crystal
Extremely hard and highly scratch-resistant. Sapphire is second only to diamond in hardness, helping keep the watch crystal clear even after years of use. - Inner Anti-Reflective (AR) Coating
A thin optical coating applied to the underside of the sapphire crystal to reduce glare and reflections, improving dial clarity in bright conditions. - Unidirectional Bezel (120-Click)
A bezel that rotates only counter-clockwise. Designed for safe timing of events — particularly underwater — with precise 120-step positioning for accurate measurement. - Screw-Down Crown & Caseback
Both crown and caseback screw securely into the case using threaded seals and gaskets, improving water resistance and protecting the movement from moisture and dust. - 20 ATM Water Resistance
Tested to withstand pressures equivalent to 200 meters. Suitable for swimming, snorkeling, and recreational diving. - FKM Rubber Strap-is a high-performance material known for its superior durability, flexibility, and resistance to heat, UV, and chemicals.It offers long-lasting comfort and retains its shape far better than standard rubber.
PT5000 Movement – Technical Specifications
- Automatic Mechanical Movement – The watch winds itself using the motion of the wrist and does not require a battery.
- Beat Rate – 28,800 vibrations per hour (28.8 kbph / 4 Hz), producing a smooth sweeping seconds hand with 8 ticks per second.
- Power Reserve – Approximately 38–42 hours. When fully wound, the watch will continue running for around 1.5 days without being worn.
- Accuracy Range – Typical regulated accuracy of approximately –10 to +15 seconds per day.
- 25 Jewels – Synthetic ruby jewels are placed at key friction points within the movement to reduce wear and improve long-term reliability.
- Shock Protection – Incabloc-style shock protection system designed to protect the balance wheel from impacts during everyday use.
- Hacking Seconds – When the crown is pulled out to set the time, the seconds hand stops, allowing precise time synchronization.
- Hand-Winding – The movement can be manually wound through the crown in addition to automatic winding.
