Orient is a Japanese watchmaker founded in 1950, now a subsidiary of the Seiko Epson Corporation. The brand is particularly well-regarded for offering high-quality in-house mechanical movements at accessible price points. Orient watches carry distinctive markings on their case backs, dials, and movements that can assist with model identification and production dating. The brand's extensive catalog of affordable mechanical watches has earned it a dedicated following among collectors and watch enthusiasts.

Serial Number Information
Orient serial numbers are typically found on the case back and often follow a format that includes information about the production date and factory. Many Orient watches display a serial number alongside a caliber and case reference number, similar to the format used by Seiko. The serial number encoding can vary by production era, and the specific coding system has not been as extensively documented by collectors as some other brands.
Some Orient watches, particularly older models, may feature serial numbers where the first digit or digits are associated with the production year. However, as with many Japanese watch manufacturers, the single-digit year code means that the serial number alone typically cannot distinguish between decades. Additional context from the model design, caliber type, and dial characteristics is commonly needed to narrow down the production date.
Modern Orient watches generally include a caliber number on the case back (such as 'F6922' or '46943') that identifies the movement. The Orient Star line, the brand's premium range, may use different serial number conventions and often features more detailed case back markings. For specific production date inquiries, contacting Orient or Seiko Epson's customer service may sometimes yield results, though historical records for older models may be limited.

Water Resistance Rating (Case Back)A marking indicating the watch's tested water resistance depth, typically shown in meters, feet, bar, or ATM. This rating describes laboratory test conditions, not actual diving depth recommendations.
Japan Movement StampA case back marking indicating the watch uses a movement manufactured in Japan. This is commonly seen as "JAPAN MOVT" or "JAPAN MOVEMENT" and denotes the origin of the caliber inside.
Clasp Code StampAn alphanumeric code stamped on the bracelet clasp identifying the clasp model and sometimes the production date. This code helps identify replacement clasps and can aid in dating the bracelet.
Bracelet End Link NumberA number stamped on the end links of a bracelet identifying their specific shape and size. This number is critical for finding replacement end links that properly fit your watch case.
Bracelet Model NumberA unique identifier stamped on the bracelet that specifies the exact bracelet model. This number is essential for ordering correct replacement bracelets or links.
Adjustable Clasp IndicatorMarkings or features on a clasp indicating it has micro-adjustment or on-the-fly sizing capability. This allows fine-tuning of bracelet fit without tools.
Lug Width MarkingA number stamped between or on the lugs indicating the distance between them in millimeters. This measurement determines which strap or bracelet width fits your watch.
Bezel Insert CodeA code identifying the specific bezel insert installed on a watch, typically relevant for dive watches and GMT models. This number is essential for sourcing correct replacement inserts.
Crown Logo StampA brand logo or emblem stamped or engraved on the watch crown. This identifies the manufacturer and can indicate whether the crown is an original or replacement part.

Jewel Count MarkingA marking indicating the number of jewels (synthetic rubies) used as bearings in the movement. This number reflects movement complexity but is not a direct indicator of quality.
Regulation MarkingMarkings on or near the movement's regulator indicating adjustment positions for timing accuracy. These are used by watchmakers to fine-tune the watch's rate.
Shock Protection SymbolA marking indicating the movement incorporates a shock protection system for the balance wheel. Common systems include Incabloc, Diashock, and Parashock.
WR 100M / 10 Bar MarkingA water resistance rating of 100 meters (10 bar/ATM), generally considered suitable for swimming and recreational water activities. Not rated for scuba diving or high-impact water sports.
WR 200M / 20 Bar MarkingA water resistance rating of 200 meters (20 bar/ATM), suitable for serious water sports and recreational scuba diving. This is the standard entry-level rating for purpose-built dive watches.
Japan Movt MarkingA case back marking indicating the watch uses a Japanese-manufactured movement. This is one of the most common markings found on affordable watches worldwide.

Frequently asked questions
Does Orient make their own movements?
Orient is widely known for producing in-house mechanical movements, which is relatively uncommon at their price point. The brand has manufactured its own calibers for decades, and this in-house production is often cited as a key differentiator. However, some Orient models, particularly quartz pieces, may use movements sourced from their parent company or other suppliers.
What does the twin lion logo on Orient watches signify?
The twin lion emblem is Orient's distinctive brand logo, which has appeared in various forms throughout the company's history. The lions are commonly depicted flanking a shield or crest. The specific design and rendering of the logo can sometimes help approximate the era of production, as the logo has evolved over the decades.
How can I identify the caliber of my Orient watch?
The caliber number is typically engraved on the case back of Orient watches, often in a format that includes both the caliber designation and a case reference number. This number can be looked up in collector databases or Orient's product documentation to identify the specific movement and its characteristics.
What is the difference between Orient and Orient Star?
Orient Star is the brand's premium line, typically featuring higher-quality finishing, more refined movements, and better materials than standard Orient watches. Orient Star models often have different case back markings, including the 'Orient Star' branding and sometimes exhibition case backs. The movements in Orient Star watches commonly have additional features such as hand-winding capability and hacking.
How water resistant are Orient dive watches?
Orient dive watches such as the Mako and Ray are typically rated to 200 meters of water resistance, which generally makes them suitable for recreational swimming and snorkeling. However, as with all watches, water resistance can degrade over time as seals age. Regular pressure testing is commonly recommended for watches that are used in water.
Is Orient related to Seiko?
Orient has been a subsidiary of Seiko Epson Corporation (a member of the Seiko Group) since 2009. While the brands operate independently and maintain distinct product lines and design philosophies, the corporate relationship means they share some resources. Orient continues to produce its own in-house movements distinct from Seiko and Seiko Epson's other calibers.
How can I tell if my Orient watch is genuine?
Authenticating an Orient watch typically involves verifying the case back markings, inspecting the movement for genuine Orient construction, and checking the dial for consistent printing quality and correct branding. Since Orient watches are generally affordable, counterfeiting is less common than with luxury brands, but modified or parts-assembled watches can appear in the secondary market.
Where are Orient watches manufactured?
Orient watches are primarily manufactured in Japan, and many models carry 'MADE IN JAPAN' markings on the dial or case back. The brand's manufacturing facilities are located in Japan, which is often highlighted as a selling point. Some components or assembly steps for certain models intended for specific markets may involve other locations, which is commonly reflected in the case back markings.
