If you want a readable everyday automatic that still looks like a cockpit instrument, the Orient Flight II is the one. The RA-AC0H03B10B (Orient also uses RN-AC0H03B and RA-AC0H03B) puts a matte black Type-B aviator dial in a 42.4 mm steel case, with large Arabic numerals, a railway minute track, and lume on the hands and markers. It is a mechanical watch you can actually see at a glance — on the desk, in the car, or after dark.
Why this Flight II works as a daily watch
Pilot watches often stop at 50 m water resistance and a push-pull crown. This one uses a screw-down crown and is rated to 100 m, so rain, washing up, and a swim are within the rating when the crown is locked. The F6722 calibre is Orient’s own automatic: 22 jewels, about 40 hours of reserve, hand-winding, and hacking seconds so you can set the time cleanly. The case is relatively slim at 11.6 mm, so it sits under a cuff better than many 42 mm sports watches.
The crystal is mineral, not sapphire — that is the honest trade-off at this price. The case back is solid (screwed), which suits a tool-style pilot more than an exhibition back. The supplied strap is black leather with white contrast stitching and a tang buckle; lug width is 22 mm if you want to swap to a NATO or bracelet later.

Who it is for
Buyers after an affordable in-house automatic with real wrist presence, a field/pilot look, and more water resistance than a typical dress watch. It is a men’s-size 42 mm, so try it if you already wear a Kamasu or a 40–42 mm Seiko 5. It is not a dive watch and it is not a dress Bambino — it sits in the field/pilot lane.

Frequently asked questions
What movement is inside the Orient RA-AC0H03B10B?
Orient calibre F6722: an in-house automatic with 22 jewels, roughly 40 hours of power reserve, hand-winding, and hacking seconds. It is the same family of in-house Orient movements used across many current Classics and sports models.
Is the Flight II water resistant enough for swimming?
It is rated to 100 metres with a screw-down crown. That is suitable for swimming and showering when the crown is fully screwed in. It is not a dive watch — do not use it for scuba. Rinse after salt water and keep the crown locked.
What is the case size of the Orient Flight RA-AC0H03B?
42.4 mm across, about 11.6 mm thick, and about 49.5 mm lug-to-lug, with 22 mm lugs. It wears like a full-size pilot, not a compact 38 mm dress watch.
Does it have a sapphire crystal?
No. Orient specifies mineral crystal on this reference. Mineral is easier to scratch than sapphire; it is also cheaper to replace. If sapphire is a hard requirement, look at Orient Kamasu or a Seiko Presage instead.
Is RN-AC0H03B the same watch as RA-AC0H03B10B?
Yes — Orient uses several catalogue codes for the same black-dial Flight II: RA-AC0H03B10B, RA-AC0H03B, RN-AC0H03B, and RA-AC0H03B10A. Confirm the black dial, leather strap, F6722, and 42.4 mm case.
