The Orient Star M34 Avant-garde F8 Skeleton RE-BZ0001S is the regular steel-bracelet sports skeleton in this line: a dual-layer silver openwork dial over Orient Star’s F8F64 automatic, with a silicon escape wheel and more than 60 hours of reserve. Named after the Pleiades (M34), it is built as a wearable sports case — screw-down crown, 100 m water resistance, sapphire front and back — not a jewellery skeleton. If you want the standard silver M34 Avant-garde rather than a limited colourway, this is the reference.
Why the RE-BZ0001S stands out
Two openworked plates stack so you can see the movement, including the blue silicon escape wheel near the small-seconds subdial at 6 o’clock. A power-reserve indicator sits on the movement. Lume on the hands and indexes keeps the layout usable after dark. The SUS316L case and bezel use hexagonal screws, brushed surfaces, and Sallaz mirror polish. The matching steel bracelet uses H-shaped links so the watch reads as one metal piece rather than a dress watch on a strap.
It suits someone who already likes Orient Star’s Contemporary M34 sports line and wants the silver openwork version with a bracelet. The 42.3 mm width and 50.0 mm lug-to-lug wear as a mid-size sports watch; 12.4 mm thickness is reasonable for a skeleton with a power-reserve train. There is no date window.
Who it is for
- Buyers who want a full skeleton Orient Star on a steel bracelet, not a nylon limited
- People who care about an in-house automatic with a silicon escape wheel, hacking seconds, and hand-winding
- Wrists that wear ~42 mm sports cases comfortably, including under a light jacket
- Anyone shopping Orient Star in Australia who wants authentic stock inspected before dispatch
Movement: calibre F8F64
F8F64 is Orient Star’s automatic calibre for this M34 skeleton, made in Japan. It was the first Orient Star automatic to use a silicon escape wheel, aimed at longer running time and stable rate. Official figures: 24 jewels, +15 to −5 seconds per day in static testing, and a power reserve of over 60 hours. Frequency is 21,600 vibrations per hour (3 Hz). Automatic winding, hand-winding, and hacking seconds are all specified. The decorated movement is visible through the sapphire case back.
Case, crystal, and bracelet
The case is stainless steel (SUS316L): 42.3 mm width, 50.0 mm lug-to-lug (case height 12–6), 12.4 mm thick. Water resistance is 10 bar (100 m). The crown is screw-down. The front crystal is flat sapphire with SAR coating; the case back is flat sapphire, screw-set, see-through. The bracelet is SUS316L, 21 mm lug width, trifold deployant clasp with push button; official wrist-size range is 140–200 mm. Weight is 180 g. Magnetic resistance is JIS Type 1 (4,800 A/m or higher). Country of origin is Japan. The line launched in May 2023.

How it compares
The Desert Luxury limited RE-BZ0005G uses the same F8F64 architecture and 42.3 / 50.0 / 12.4 mm case, with gold-colour plating and a khaki nylon strap, limited to 300 pieces. RE-BZ0001S is the ongoing silver steel-bracelet watch. If you want a smaller open-heart dress piece rather than a sports skeleton, the M34 F7 Semi Skeleton (for example RE-BY0004A) is 40.0 mm with F7F44 and a 50-hour reserve. Classic Orient Bambino models stay closed-dial and more affordable.

Frequently asked questions
What is the water resistance of the Orient Star RE-BZ0001S?
Official water resistance is 10 bar (100 m), with a screw-down crown. That covers swimming and shower splash. It is not a 200 m diver; treat the exhibition back with the same care you would any sapphire sports watch.
What movement does the RE-BZ0001S use?
In-house Orient Star calibre F8F64: automatic with a silicon escape wheel, hand-winding, hacking seconds, 24 jewels, over 60 hours of power reserve, rated +15 to −5 seconds per day in static testing.
Is the RE-BZ0001S a limited edition?
No. RE-BZ0001S is the regular silver openwork model on a steel bracelet. Limited colourways in the same family (for example the Desert Luxury RE-BZ0005G) are numbered separately.
Does the RE-BZ0001S have a date window?
No. The dual-layer skeleton layout uses small seconds and a power-reserve indicator instead of a date.
What size is the M34 Avant-garde F8 Skeleton case?
42.3 mm width, 50.0 mm lug-to-lug, 12.4 mm thick, 21 mm lug width. Official weight is 180 g including the steel bracelet.
Is the Orient Star RE-BZ0001S suitable as an everyday watch?
Yes for daily sports-dress wear: 100 m water resistance, screw-down crown, lume, and a steel bracelet. The openwork dial is more showpiece than a tool watch with a solid dial; if you need a closed diver, look at Orient’s Kamasu/Mako line instead.
