If you want a quiet Orient Star dress watch rather than a sports diver, the Orient Star M45 F7 Small Second RE-BS0002S00B is built for understatement. An ivory dial with sandblast and sunburst texture, leaf hands, Roman numerals and a railway minute track sit under dual-curve sapphire. Small seconds live at 6 o’clock; the brand’s power-reserve indicator sits cleanly at 12. There is no date window — the layout stays balanced and classical.
Inside is Orient Star’s in-house mechanical calibre F7H44: automatic winding, hand-winding and hacking seconds, 24 jewels, static accuracy of about +15 to −5 seconds per day, and more than 50 hours of power reserve. The movement is finished to Orient Star standards and shown through a sapphire exhibition case back on a screw-down back.
Why this M45 stands out
- True small-seconds dress layout — hours and minutes on the main dial, running seconds on a recessed subdial, not a central seconds hand competing with the dress face.
- Power reserve you can read — the 12 o’clock indicator helps you plan winding before a weekend off the wrist.
- Compact M45 proportions — 39.0 mm width, 45.7 mm lug-to-lug and 11.7 mm thickness wear easily under a cuff.
- Premium crystal stack — dual-curve sapphire with SAR anti-reflective coating on the front; sapphire on the exhibition back.
- Brown leather with deployant — 20 mm strap, push-button trifold clasp, intended wrist range roughly 150–190 mm.
- Everyday practicality without sports bulk — SUS316L steel case, about 76 g on the leather strap, 3 bar (30 m) water resistance for rain and hand washing only.
Who it suits
Buyers stepping up from mainline Orient Bambino or Seiko dress pieces who want Orient Star finishing, an in-house F7 movement and a no-date small-seconds face. It works for office wear, formal evenings and collectors who prefer Japanese mechanical watches with clear classical design language over loud limited-edition graphics.

Frequently asked questions
What movement is inside the RE-BS0002S00B?
Orient Star calibre F7H44 — a Japanese in-house mechanical automatic with hand-winding, hacking seconds, 24 jewels and over 50 hours of power reserve. Official static accuracy is about +15 to −5 seconds per day.
Does this Orient Star have a date window?
No. The M45 F7 Small Second layout is deliberately date-free so the ivory dial stays open, with small seconds at 6 and power reserve at 12.
What are the case dimensions?
39.0 mm case width, 45.7 mm lug-to-lug and 11.7 mm thickness. Lug width is 20 mm. That places it firmly in compact dress-watch territory rather than modern sports sizing.
Is the crystal sapphire?
Yes. The front glass is dual-curve sapphire with SAR anti-reflective coating. The exhibition case back also uses sapphire so you can see the F7H44 finishing.
How water resistant is the RE-BS0002S00B?
3 bar (30 m). Treat it as a dress watch: rain and hand washing are fine; swimming, showering and diving are not.
