The Orient Stretto RA-AK0316L30B is the Day & Night limited edition: a navy dial with an orange day-of-week disc at 10 o’clock, a turquoise sun-and-moon indicator in the lower half, and a date window at 3. It is a contemporary dress watch on a steel bracelet, not a small Bambino and not a diver.
Who it suits
Buy this if you want a mechanical Orient with a real complication and a bit of colour, in a modern 41.5mm case. The Stretto case is larger and cleaner than a classic Bambino, and the dial does the talking. It is a desk and evening watch. Fifty metres of water resistance covers rain and handwashing. It is not a swim watch.
What you actually see on the dial
The dial is deep navy, with orange rings under the hour markers and a pink minute track. The applied indexes are silver with orange tips. Hour and minute hands are silver. The seconds hand is a thin lime green.
The gold-orange disc at 10 shows the day of the week. The turquoise disc below centre shows sun and moon as the day turns to night. That lower disc is an indicator, not an open-heart window onto the movement. The date sits in a small window at 3. Orient prints the logo and the word Automatic under 12. The crown is a simple push-pull at 3, with no crown guards.
Movement and case
Inside is Orient calibre F6B24. It is an automatic with hand-winding and a hacking seconds hand, so you can stop the seconds and set the time against a reference clock. Power reserve is about 40 hours. The exhibition caseback is engraved twenty-two jewels, stainless steel, front sapphire crystal, and water resistant 5 bar. It also reads made in Thailand. You can see the rotor without opening the watch.
Orient’s published case size for this reference is 41.5mm across, 13mm thick, and 48mm lug to lug, with 22mm between the lugs. Those figures match the size attributes already on this page. The bracelet is stainless steel with a foldover clasp. The crystal is sapphire, which is the practical upgrade over the mineral crystal on many Bambino references: clearer, and harder to scratch in a bag or at a desk.
Stretto Day & Night versus Bambino sun and moon
Both families can show day and night, but they are not the same watch. A classic Bambino sun and moon is usually a smaller dress watch, often on leather, often with a mineral crystal and 30m water resistance. This Stretto is the newer Contemporary case: 41.5mm, sapphire, steel bracelet, 50m, and a busier coloured dial. If you want a quiet cream dial and a leather strap, look at a Bambino. If you want the complication in a sportier polished case, this is the one.
Orient sells this reference as a Day & Night limited edition. It is not sold as a numbered piece with a published production total, so treat “limited” as the collection name, not a serial-numbered run.

Questions buyers ask
What movement is in the Orient RA-AK0316L30B?
Orient calibre F6B24. It winds as you wear it, and you can also hand-wind it. The seconds hand hacks when you pull the crown, which makes setting the time easier. Reserve is about 40 hours. The caseback is engraved with twenty-two jewels.
What does the day and night indicator show?
Two separate displays. The orange disc at 10 o’clock is the day of the week. The turquoise disc in the lower half of the dial shows a sun and a moon so you can see whether the 24-hour cycle is in day or night. The date is a third, smaller window at 3 o’clock.
How big is the Orient Stretto RA-AK0316L30B?
41.5mm across, 13mm thick, 48mm from lug to lug, and 22mm between the lugs. On a wrist that is a modern dress-sport size: bigger than a 38mm Bambino, smaller than a 45mm sports watch. The steel bracelet wears straightforwardly. If you prefer leather, the 22mm lug width is a common strap size, but this watch is supplied on the bracelet.
Is the RA-AK0316L30B water resistant enough for swimming?
No. Orient rates it to 50 metres, and the caseback reads 5 bar. That is everyday resistance: rain, washing hands, a splash. It is not rated for swimming, showering as a habit, or diving. The crown is push-pull, not a screw-down diver crown.
How is this different from an Orient Bambino sun and moon?
The Bambino sun and moon is the classic small dress watch, usually leather and mineral crystal. The RA-AK0316L30B is a Stretto: larger Contemporary case, sapphire crystal, steel bracelet, 50m, and a much more colourful dial. Same broad idea of a day-and-night complication. Different watch on the wrist.
