Orient Star has introduced a new anniversary model in three variations.
The Orient Star M45 F7 Small Second watches are available in green and ivory as part of the regular collection, while the dark gray version is limited to 500 pieces. This line is crafted in a classic style with a harmonious dial layout. The small seconds subdial is positioned at the 6 o'clock mark, and the power reserve indicator is at 12 o'clock. The elongated Roman numerals remain fully legible despite the additional subdials. The design features elegant leaf-shaped hands and one of the most discreet power reserve indicators among Orient Star models. The 316L stainless steel case measures 39 mm in diameter and 11.7 mm in thickness, maintaining classic proportions.
Classic and Modern: Orient Star Anniversary Series
The celebration of Orient Star's 75th anniversary continues. The full collection was unveiled in February, but details were revealed gradually. The astronomical model M34 F8 Date Meteorite and the marine diver M42 Diver 1964 have already been reviewed. The new M45 F7 Small Second model features a more restrained style aimed at everyday use. Nevertheless, the cosmic theme remains - inspired by the Pleiades star cluster, also known as the "Seven Sisters" or Subaru (昴). The Japanese car manufacturer Subaru even uses this cluster in its logo.
Design Features and Functionality of Orient Star M45 F7 Small Second
Although the dark gray variant is declared the flagship of the collection, the green version deserves special attention. Like all Orient Star models since the 1990s, these watches feature a power reserve indicator. Despite the automatic movement, this indicator is useful as watches with 30 m water resistance and classic design may not be worn over the weekend. Unlike the more sporty M42 Diver 1964 model, the M45 F7 Small Second is intended for daily wear and requires timely winding.
The power reserve indicator helps the owner understand when winding is needed. If the small leaf-shaped hand points near the "11 o'clock" position, it's time to wind the watch. A few turns of the crown will move the hand closer to the "1 o'clock" mark, providing a week's worth of energy.
Dial Color Variants: Green, Ivory, and Dark Gray
The green dial's color scheme varies between the main surface and the fan-shaped power reserve scale. The shade is closer to pine green, adding color without disrupting the elegance of the classic style. The integrated seconds subdial has a sunburst finish that beautifully contrasts with the textured surface of the main dial. A railroad track-style minute track ensures precise time setting.

The ivory option maintains the same layout but creates a softer visual impression. The contrast between elements is reduced, giving the dial uniformity. At first glance, the power reserve scale appears monochromatic, which is confirmed under restaurant lighting. However, upon closer inspection, a slight difference in shades is noticeable, also affecting the seconds counter. If a cleaner and more neat appearance is preferred, ivory is the optimal choice.
The limited edition in dark gray (500 pieces) features a grainy dial texture and a sandblasted finish on the small seconds subdial. This variant most vividly expresses the cosmic theme of the collection - the dial resembles a clear night sky filled with stars. The Roman numerals are printed in white, as in the green version. Meanwhile, the ivory model uses black numerals and hands, as well as a matching logo at the 3 o'clock mark.
Case and Ergonomics
All versions have a case diameter of 39 mm and a lug-to-lug length of 45.7 mm. For classic watches, this is a slightly larger size, yet they remain comfortable for most wrists. The tapered crown ensures an easy grip, and the polished bezel adds sophistication to the piece.

Technical Specifications and Movement
The case back features a sapphire crystal, revealing the signature F7H44 caliber. The steel rim around the transparent window is engraved with the limited edition number and the commemorative "75th Anniversary" inscription (only for the dark gray version). The movement rotor is adorned with the brand's logo and a wave pattern. The F7H44 caliber is characterized by accuracy with an allowable deviation of -5 to +15 seconds per day, which is a conservative yet competitive specification in this price segment. For comparison, the Seiko 4R35 movement allows for a deviation of -35/+45 seconds per day, making the F7H44 a more accurate choice.

Straps and Package
The green and ivory models come with brown leather straps and a stainless steel push-button clasp. The limited dark gray version is equipped with a black leather strap with a similar clasp.
Price and Availability
All models are now available for purchase. The green and ivory versions are priced at €999.99 / £869.99, while the limited edition with a dark gray dial costs €1,049.99 / £912.99.

Final Impressions and Recommendations
After personally examining the three versions, the limited edition attracted me less than expected.

The ivory dial appeared the most harmonious and balanced due to its purity and versatility. However, the choice depends on personal preference. Which version do you find most appealing? Share your thoughts in the comments.
