| Period |
Models and development
|
|---|---|
| 1950–1951: The beginning of the brand | Orient was established in 1950 at the Tama Keiki Company; in 1951, the company was renamed the Orient Watch Company. The Orient Star also appeared in 1951 as a higher-end mechanical line. Early versions were predominantly classic hand-wound watches. |
| 1950s: Early Orient Star and calendar watches | Orient expanded its mechanical range. The Orient Star received various executions, including models with a small seconds hand and later an automatic movement. During this time, the development of watches with calendar functions also began, which would become important for later Orient series. |
| 1960s: Sporty and technically sophisticated models | The Grand Prix 100 represents higher-end automatic Orient watches. In 1964, the Olympia Calendar was released, an automatic watch with a calendar display. 1967 saw the follow-up of the very slim automatic Fineness. Early World Diver models with additional time zone or world time displays also originated from this era. |
| 1960s–1970s: Diver and world time watches | Orient continued to develop robust sports watches and diver watches. Well-known historical names include the King Diver and World Diver. Depending on the version, they differ significantly in terms of cases, dials, bezels, and movements; the names alone therefore do not allow for precise dating. |
| 1970s: Mechanical watches and quartz | Orient continued to produce mechanical models, but—like many manufacturers—expanded its range to include quartz watches. These include various Orient Quartz models and higher-positioned quartz watches, such as those from the Orient Star family. |
| 1980s–1990s: Diverse series | The range included both quartz and mechanical models. Orient Star remained the premium line; alongside this, numerous dress, sports, and calendar watches appeared. Many models carry technical reference codes rather than permanently recognized collection names. |
| 2000s: Return of popular automatic models | The Mako became one of the most well-known modern Orient diver watches. The Orient Star Retro-Future stood out with its unusual skeletonized or technically inspired dial. The Orient Star Classic continued classic dress watch design. | 2000s–2010s: Mako, Ray, and Bambino | Alongside the Mako, the similarly oriented Ray series became popular. Both appeared in multiple generations and variants, such as with different bezels, dials, and movements. The classic Bambino developed into a well-known dress watch family; there are numerous variants and generations with various dial and case shapes. |
| 2010s: Further sports and dress lines | Orient continued the Mako and Ray diver watch families and supplemented the range with sporty models like the Kamasu. Regarding classic watches, the Bambino and Orient Star Classic were further developed. More elaborate lines such as Orient Star Contemporary and Orient Star Sports also appeared within the Orient Star collection. |
| 2017: Organizational integration | Orient and Orient Star were integrated into the Seiko Epson Corporation. The brands remained in existence and continued their model families. |
| 2020s: New generations and reissues | The Mako, Kamasu, Bambino, and Orient Star were continued with updated movements and features. Orient also released reissues and variants more strongly oriented toward historical models. In diver watches, the Mako remains a central series; in classic watches, the Bambino remains particularly well-known. |

With Orient, the exact year of manufacture usually cannot be identified by the model name alone: Mako, Ray, and Bambino have been offered for a long time in several generations and with different references. For dating a specific watch, the reference code and serial number on the case back, as well as the movement designation, are helpful.
