Audemars Piguet Royal Oak Offshore 15710ST.OO.A010CA.01 – Dealer Reference Guide
What Is the 15710ST.OO.A010CA.01?
The 15710ST.OO.A010CA.01 is Audemars Piguet's steel-cased Royal Oak Offshore chronograph, representing the core production reference in the Offshore line. This 42mm integrated bracelet sports watch combines AP's signature octagonal bezel with a tachymeter-equipped dial and chronograph functionality—the formula that has defined the Offshore since 1993.
The "ST" designation confirms stainless steel construction. The reference is in continuous production with minor updates, making it one of the most accessible entry points into the Offshore family for secondary market buyers. Retail MSRP sits around $20,500 USD.
Key specs:
- Case: 42mm stainless steel
- Movement: Caliber 3126 (self-winding chronograph)
- Water resistance: 100m
- Bracelet: Integrated steel (not interchangeable with rubber strap variants)

Should You Buy It?
Verdict: HOLD / SELECTIVE BUY
Pros:
- Moderate velocity (1.6/mo) ensures consistent secondary demand
- 92% box inclusion rate signals strong collector care
- Steel sports chronographs remain resilient across market cycles
- Retail premium ($20.5k) provides 15–20% margin potential on clean examples
Cons:
- Flat price trend (-0.5%) indicates no appreciation momentum
- Only 67% papers—missing documentation reduces buyer confidence and resale speed
- 42mm case size polarizes modern buyers (some prefer 41mm alternatives)
- Competitive with newer Offshore references (15710ST.OO.A027CA.01) at similar price points
Recommendation: Buy selectively if you can source sub-$14,500 examples with full papers and box. Avoid overpaying for "investment" potential; this reference is a hold-and-flip play, not an appreciating asset. Ideal for dealers with established Offshore clientele or those building balanced sports watch inventory.
FAQ
Q: What's the difference between this reference and the newer 15710ST.OO.A027CA.01?
A: The 15710ST.OO.A027CA.01 (released ~2021) features a revised dial layout and updated movement. Secondary market pricing is nearly identical ($17,000–$18,500), but the newer reference has stronger collector demand. The 15710ST.OO.A010CA.01 is the "outgoing" reference—useful for buyers seeking lower entry prices.
Q: How much does missing papers affect resale value?
A: Based on auction data, examples without papers typically sell 5–8% below median ($17,800), landing around $16,400–$16,900. Papers add confidence and appeal to international buyers; prioritize complete sets for faster turnover.
Q: Is this watch still in production?
A: The 15710ST.OO.A010CA.01 remains in AP's catalog but is being phased out in favor of newer Offshore references. Secondary market supply is stable; retail scarcity is not a factor.
