The Orient Star RE-AZ0105N is the 75th-anniversary M34 F8 Skeleton: a compact 39 mm full-openwork watch built around a hand-wound F8B65 movement with a meteorite-style finish. It is a dress-leaning piece for someone who wants the movement on show every hour of the day, not a tool diver and not a quartz daily beater. Limited to 430 pieces (300 for Japan, 130 for export). Shop it as a Japan-made Orient Star from Chronospride in Australia.
Orient’s Contemporary M34 case is short lug-to-lug for the diameter, so 39.0 mm does not wear like a 42 mm fashion watch. Grey plating on the mid-case and bracelet sits against a brighter steel bezel and crown. The ring-shaped openwork dial uses Roman numerals and indexes on a black-to-grey gradation; there is no date window. A power-reserve display sits on the movement architecture. Front crystal is dual-curve sapphire with SAR coating; the exhibition back is flat sapphire. Water resistance is 50 m — fine for rain and a sink, not for swimming as a habit.
Who the RE-AZ0105N suits
Buyers who already like Orient Star’s M34 shape and want a true skeleton rather than a small open heart. The extra black cordovan strap (push-button deployant) is in the box if the plated bracelet is too formal. Hand-winding is the daily ritual here: this calibre is not an automatic. If you want a rotor and 100 m, look at the M34 F8 Date line instead.

Why this skeleton is different from an open-heart Star
Open-heart models leave a window over the balance. The RE-AZ0105N cuts the dial into a ring so the F8B65 sits in full view, including the blue silicon escape wheel. Laser processing on both faces of the movement is meant to read like a crystalline meteorite, which is the 75th-anniversary story, not a marketing nickname for a standard F8 finish. The comet-shaped balance bridge is part of that same M34 F8 skeleton architecture.
Thickness is 10.8 mm. That is slim for a skeleton with a dual-curve crystal. The trade-off is 50 m water resistance and a plated bracelet that will show wear over years the way any plated steel does. Treat it as a dress/weekend watch.
Wearing and care
Hand-wind in the same direction until the stop-click; do not force past it. Seventy hours of reserve means a Friday wind can cover a quiet weekend, but it will stop if it sits unworn through a working week. Keep water away from the crown. The extra cordovan strap needs the same care as any leather: dry wrists, no shower.
Frequently asked questions
What movement does the Orient Star RE-AZ0105N use?
In-house calibre F8B65: hand-winding only, 22 jewels, factory static accuracy +15 to −5 seconds per day, more than 70 hours of reserve, hacking seconds, and a silicon escape wheel. It is based on F8B61 with a meteorite-style laser finish on this limited run. It is not an automatic.
Is the RE-AZ0105N a limited edition?
Yes. Orient lists 430 pieces worldwide (300 for the Japanese market, 130 for export). The exhibition back carries 75th-anniversary text and a serial number. The store SKU is RE-AZ0105N00B.
What is the water resistance of the RE-AZ0105N?
50 metres (5 bar). That covers rain and hand washing. It is not a dive watch. The M34 F8 Date models are the 100 m option in the same Contemporary family.
What size is the case?
39.0 mm across, 46.5 mm lug-to-lug, 10.8 mm thick, 20 mm lugs. Manufacturer weight is 142 g on the steel bracelet.
Does it come with a leather strap as well as the bracelet?
Yes. Orient includes a black cordovan strap with a push-button trifold clasp in addition to the grey-plated steel bracelet.
Is the RE-AZ0105N suitable for everyday wear?
As a dress or office watch, yes, if you are happy to wind it. Sapphire crystal and 50 m resistance handle a normal day. Skip it for swimming, gym work, or jobs that bang the case. There is no lume for night reading.
