Introduction
The Orient Sun & Moon ref. RA-AK0007S is a dress watch that punches above its weight class. For the trust-fund-baby collector looking for a daily beater with a touch of elegance, this Japanese automatic offers a unique sun and moon complication at a fraction of the cost of Swiss alternatives. But does it hold its value? Let's dive into the data.
In a market flooded with sterile quartz dress watches, the Sun & Moon stands out with its in-house automatic movement and a dial that tells you whether it's day or night. It's a conversation starter without the six-figure price tag. However, the resale market tells a different story – depreciation is steep, making this a watch to buy pre-owned or keep forever.
We've analyzed the specs, movement, wrist feel, and investment potential to give you the full picture. Whether you're adding to a growing collection or looking for a first mechanical, here's everything you need to know about the Orient Sun & Moon.
Manufacture History
Orient Watch Co., Ltd. was founded in Tokyo in 1950 and quickly became known for producing reliable, in-house mechanical movements at accessible prices. The Sun & Moon line, introduced in the 2010s, exemplifies Orient's philosophy of offering complications typically reserved for luxury watches at a fraction of the cost. This model, ref. RA-AK0007S, is a staple of the collection, blending classic dress watch proportions with a whimsical day/night indicator.
Movement
The Caliber 40N5A is a workhorse automatic movement with 22 jewels, a 40-hour power reserve, and a beat rate of 21,600 vph. It's not COSC-certified, but it is entirely in-house – a rarity at this price point. The movement features basic perlage decoration visible through the exhibition caseback. The sun and moon disc is driven by a 24-hour wheel, providing a simple yet charming visual cue for AM/PM. While finishing is utilitarian, the movement is robust and easy to service.

Wrist Feel
The 41mm case wears slightly larger due to the thin bezel, but the curved lugs keep it comfortable on a 7-inch wrist. The leather strap is stiff out of the box but breaks in after a few wears. Weight is moderate – not too heavy, not too light – making it suitable for all-day wear. The crown is easy to grip and operates smoothly. Overall, it's a balanced, unobtrusive dress watch that doesn't scream for attention.
Accuracy
Expect around -20 to +40 seconds per day out of the box. This is typical for an unregulated Orient automatic. Regulation by a watchmaker can bring it to within -10/+20 seconds, but it's not a precision instrument. For daily wear, the variance is acceptable, but if you need chronometer-level accuracy, look elsewhere.
Occasions
The Orient Sun & Moon is best suited for dress, daily, and formal occasions. Its classic design pairs well with suits or casual wear, though the 50m water resistance means you should avoid swimming.
Wrist Presence
3/5 – The sun and moon dial draws attention, but the case is understated. It's a conversation starter without being flashy. The domed mineral crystal adds a vintage touch, but the lack of AR coating can cause glare in bright light.
Reference Variants
The RA-AK0007S is part of a family with several dial options: RA-AK0001S (white dial), RA-AK0002S (black dial), and RA-AK0003S (blue dial). All share the same case and movement, differing only in dial color.
Family & Other Models
The Sun & Moon series includes multiple references with similar complications. Other notable Orient models include the Bambino (dress), Mako III (diver), and Kamasu (diver).
Similar Watches
In the same price bracket, the Seiko Presage Cocktail Time offers a similar dress watch experience with a more refined movement. The Tissot Le Locle is a Swiss alternative with a classic design, though at a higher price.
Homages
For those on a tighter budget, the Pagani Design PD-1694 offers a similar sun/moon complication with an automatic movement for under $100.
Investment Value
MSRP is $350, but pre-owned prices range from $150 to $250. The trend is depreciating – this watch loses value quickly after purchase. Our recommendation: buy pre-owned to avoid the initial hit. There is no notable auction history.
Service Interval
Service every 5 years, costing approximately $250. Authorized service is not required; any competent watchmaker can handle it. Parts are readily available.
Pros & Cons
Pros: Unique sun and moon complication, in-house automatic movement, affordable price point, exhibition caseback.
Cons: Mineral crystal scratches easily, only 50m water resistance, movement accuracy is average, strap feels cheap initially.
Final Verdict
The Orient Sun & Moon is a charming dress watch that offers a lot of bang for the buck. While it won't appreciate in value, it's a reliable daily wearer with a distinctive dial. For the young collector, it's a solid entry-level piece that teaches the joy of mechanical watches without breaking the bank. Buy pre-owned, wear it in good health, and don't expect a return on investment.
