Orient Star Diver 1964 1st Edition

Orient Star has introduced a new Diver 1964 1st Edition model to its Sports Collection, limited to 900 pieces worldwide. Created in 1951, Orient Star has dedicated itself to producing high-quality, Japan-made mechanical watches that are “shining stars” and fuse traditional craftsmanship with the latest watchmaking technologies. This new limited-edition model reflects the brand’s proud history, reproducing the original design of the Olympia Calendar Diver*¹ model, released in 1964, with the upgraded contemporary scuba divers’ watch specification of 200-metre water resistance, in compliance with the ISO 6425 standard. This exceptional model features the same silver dial as the original and combines vintage design with Orient Star’s latest high-performance in-house movement.

With sporty and relaxed styling gaining popularity across generations, divers’ watches and vintage designs have become a worldwide trend. The Diver 1964 1st Edition launched in 2021 for Orient Star’s 70th anniversary and attracted attention from the outset, soon becoming popular all over the world. This new version, which features a silver dial, is the latest model in the line-up.

The Diver 1964 1st Edition is based on the Olympia Calendar Diver which was launched after several years of development that began in the early 1960s. The new model reproduces the same features as the original; a rotating bezel made of solid stainless steel, three-dimensionally cut indices, an arrow-shaped hand, and a case shape with sharp lugs.

The Olympia Calendar Diver was available in black or silver dials, with the latter now extremely rare and only a few original pieces in existence. This new model is a reproduction of the silver version. The metallic feel of the silver dial gives this divers' watch a dressier look, and yet the contemporary design makes it ideal for sport settings, as well as everyday use.

The case is made of high-quality stainless steel (SUS316L) and features a screw-down crown, a screw case-back, and sapphire crystal with anti-reflective coating. It offers a significantly improved water resistance of 200 metres for scuba diving, which is compliant with the ISO 6425 standard for divers' watches and is a significant improvement from the original model’s 40 meters . The metal bracelet is made from the same high-quality stainless steel and provides substantial presence and optimum comfort on the wrist. The trifold clasp comes with push button, security latch and divers’ extension, making the watch practical to use for sports activities and urban lifestyles.

The hand-wound movement of the original 1964 model has been replaced with a contemporary automatic movement, an in-house caliber F6N47 that provides stable high accuracy, and a 50-hour power reserve. Another new feature is the indicator which shows the power reserve’s remaining running time. Although most Orient Star models come with a power reserve indicator as standard , it is rare to find this feature on divers’ watches.

  •  The original 1964 model does not meet current ISO standards as there were no clear standards for divers’ watches at the time. Currently not for sale.
  •  Not including ladies’ models.

About Orient Star

Established in Japan in 1951, Orient Star originates from a desire to create a mechanical watch that would become a “shining star” in every aspect, including design, components, and manufacturing. Orient Star continues to shine and innovate its technology as well as the design of its beautiful timepieces. The Skeleton models, launched in 2021 are mounted with the latest movement with silicon escape wheel for longer power reserve and beauty, incorporating design inspired by the vast universe. The brand continues the theme of “NOWHERE, NOW HERE” (meaning, it was nowhere else to be found, but it's here now). Traditional skills to achieve intricate craftsmanship, in-house production system to create high-quality mechanical movements, and original designs, are all incorporated for these unique, made-in-Japan watches. Orient Star will continue to deliver these creations in Japan and throughout the world.
