Orient Automatic Mako III Kamasu RA-AA0820R39B Men's Watch (41.8mm Case) The Orient men's watch from the iconic and internationally acclaimed Mako / Kamasu series with the reference number RA-AA0820R39B is an absolute icon among automatic "diver" watches. The design of this model combines uncompromising Japanese reliability, masterful craftsmanship and the highly desirable Burgundy dial (Crimson/Burgundy Red). It is an ideal proposition for demanding men looking for a prestigious mechanical watch with a sporty flair, which will be perfect for the most difficult conditions, as well as during elegant meetings. ✨ Design & Design – Deep Burgundy & Classic Diving Chic Prestigious Burgundy Sun Cut Dial: The unique dark red dial in burgundy reacts spectacularly to light, changing its colour from a saturated red to an elegant deep black. Two-tone Rotating Bezel: The one-way diving ring (120 clicks) with a burgundy-black aluminum liner allows you to precisely count down the time spent underwater or parking time. Robust Stainless Steel Construction: Both the massive case and the classic three-row bracelet are made of premium 316L stainless steel, fully anti-allergic and resistant to seawater. Powerful Luminous Luminescence: Thick, geometric indices and distinctive, sharp hands are generously filled with advanced luminescent mass, guaranteeing excellent legibility in the absolute depths of the ocean or at night. ⚙️ Manufacture Automatic Movement – Japanese Heart Custom Calibre Orient F6922: The heart of the watch is the legendary Japanese automatic movement (In-House) bearing on 22 jewels. The watch winds itself by moving your wrist while wearing. Stop-Second (Hacking) and Tightening function: The mechanism allows you to manually tighten the spring with the crown and stop the second hand for perfectly precise time setting. Independent Power Reserve: It is more than 40 hours, which means that a watch set aside for the weekend will accurately time until Monday. 🌊 Professional 20 ATM water resistance and Sapphire Glass The Orient Mako III meets the stringent requirements for professional sports watches by offering advanced security systems: Sapphire Glass: Highest scratch protection class (9/10 on the Mohs scale). It is inferior in hardness only to diamond, guaranteeing impeccable clarity for decades. 200M (20 ATM) water resistance class: Allows you to swim freely, jump into the water, practice water sports and scuba dive to considerable depths. Screw-down Crown and Caseback: Additional sealing of key components of the structure effectively blocks moisture from entering the inside of the case. Important tip: Before each entry into the water, it is imperative that the crown of the watch has been tightened to the maximum and correctly (locked on the thread). After bathing in salty seawater, it is recommended to rinse the watch under running fresh water. 📊 Product Specification Parameter Product Details Brand / Collection Orient / Sports Diver (Mako III / Kamasu) Product code (Model) RA-AA0820R39B / RA-AA0820R Movement origin Japan (Made in Japan / In-House) Movement type Automatic (Orient F6922, 22 stones) Power reserve Approx. 40 hours Case and bracelet material Stainless steel 316L (Anti-allergic, stainless) Case diameter 41.8 mm (Iconic, optimal male size) Case thickness 13.0 mm (Provides a solid, Case & Bracelet Color Silver (Silver) Dial Color Burgundy / Red (Sunshine) Glass Type Sapphire (Extremely Scratch Resistant) Water Resistance 20 ATM / 200 m (Professional Diving) Additional Features Dual Date Display (Day of the Month + Day of the Week), Screw-Down Crown, Screw-Down Caseback, Rotating Bezel, Stop-Second, Luminescent Coating
