The Orient Star Classic collection offers a quieter interpretation of premium watchmaking. Instead of oversized cases, rotating bezels, or highly technical displays, it focuses on balanced proportions, refined dial textures, traditional hands, and mechanical movements made for enthusiasts.
This review focuses on the Orient Star M45 F7 Small Second RE-BS0001E. Its green dial, compact stainless-steel case, small-seconds display, and visible in-house movement combine vintage character with modern Japanese engineering.
Quick verdict: The Orient Star Classic is ideal for buyers who appreciate restrained luxury, mechanical details, and a design that rewards close inspection.
The Design in Three Layers
The RE-BS0001E looks simple from a distance, but its personality becomes clearer as the wearer examines each part of the watch.
Layer One: The Green Dial
The green dial has a gentle finish rather than the aggressive shine found on some modern sports watches. Its color can appear lighter or darker depending on the angle and surrounding light.
Orient Star uses a small-seconds subdial instead of placing the seconds hand at the center. This arrangement gives the watch a traditional appearance while adding movement to the lower section of the dial.
The display does not include a date window. That decision preserves symmetry and prevents the textured dial from becoming crowded.
Layer Two: The Power Reserve Indicator
A power reserve indicator shows approximately how much energy remains inside the mechanical movement. It is particularly useful on an automatic watch because it lets the owner know whether the movement needs additional winding.
The indicator also gives the dial a recognizable Orient Star identity. Unlike a decorative subdial, it provides information that directly affects the ownership experience.
Layer Three: The Mechanical Case Back
The sapphire exhibition case back reveals the in-house F7H44 movement. Owners can observe the automatic winding rotor and some of the components responsible for transferring energy through the watch.
This view creates a more personal connection with the watch. The movement is not hidden behind a solid steel cover, so part of the mechanical craftsmanship remains visible whenever the watch is removed.
Technical Profile

|---|---|
| Reference | RE-BS0001E |
| Movement | F7H44 mechanical automatic |
| Manual winding | Yes |
| Power reserve | More than 50 hours |
| Stated accuracy | +15 to -5 seconds per day |
| Case diameter | 39 mm |
| Case thickness | 11.7 mm |
| Lug-to-lug height | 45.7 mm |
| Case material | SUS316L stainless steel |

The F7H44 is an in-house mechanical caliber with automatic winding, manual winding, hacking seconds, 24 jewels, and a power reserve exceeding 50 hours. The official specification lists an accuracy range of +15 to -5 seconds per day under stated testing conditions.
How the 39 mm Case Wears
The 39 mm diameter is one of the model’s greatest strengths. It feels contemporary without abandoning the more restrained proportions associated with vintage dress watches.
Its 45.7 mm case height from lug to lug should help it remain controlled on many medium-sized wrists. At 11.7 mm thick, it has enough depth to show the curved dial and mechanical movement without becoming excessively bulky.
The elongated lugs add elegance and make the watch appear slightly larger than its diameter suggests. Trying it on remains important because lug shape can influence fit as much as case width.
A Watch for Quiet Occasions
The brown leather strap and green dial pair naturally with:
- Navy or charcoal suits
- Cream knitwear and tailored trousers
- Brown leather shoes and accessories
- Dark denim with a button-down shirt
- Olive, tan, burgundy, and earth-tone clothing
The watch can move between professional and smart-casual settings without looking overly formal. Its colors also provide more individuality than a standard black or white dress watch.
What It Does Especially Well
Advantages
- Compact and versatile 39 mm case
- In-house Japanese mechanical movement
- Useful power reserve indicator
- Small-seconds display with vintage character
- Sapphire crystal on the front and back
- Manual winding and hacking functionality
- Refined green dial
- Visible movement through the case back
Possible Drawbacks
- The 30-meter water-resistance rating is limited
- Leather should be protected from moisture
- No date display
- Mechanical accuracy cannot match most quartz watches
- The power reserve is shorter than some 80-hour competitors
- The understated design may appear too conservative to some buyers
Who Should Choose the Orient Star Classic?
This watch makes sense for someone who already understands the appeal of mechanical movements and wants a more refined experience than an entry-level automatic watch provides. It can also serve as an introduction to premium Japanese watchmaking for buyers who prefer subtle design over recognizable luxury branding.
It is not intended to be a rugged all-purpose watch. Buyers who regularly swim, work outdoors, or require stronger impact resistance should consider a sports model.
Final Verdict
The Orient Star Classic M45 F7 Small Second demonstrates that elegance does not require visual excess. Its compact dimensions, textured green dial, power reserve indicator, small seconds, and visible in-house movement create interest without sacrificing balance.
Its modest water resistance limits its versatility, but that is consistent with its dress-oriented purpose. For collectors seeking quiet Japanese craftsmanship and vintage-inspired proportions, the RE-BS0001E offers a distinctive alternative to mainstream Swiss options.
