AP Royal Oak Chronograph Comparison: 26240 vs 26331 vs 26420 – Which 1:1 Super Clone is Right for You?

AP Royal Oak Chronograph: 26240 vs 26331 vs 26420 – A Complete Buyer’s Guide

Audemars Piguet’s chronograph offerings are among the most sought-after luxury sports watches. For replica collectors, three models stand out: the 26331 (the classic), the 26240 (the modern 50th anniversary upgrade), and the 26420 (the rugged Offshore). While all feature the iconic octagonal bezel and integrated bracelet/strap, they cater to different wrist sizes, design preferences, and budgets.

In this guide, we break down every difference to help you choose the perfect AP chronograph replica.

2. Size & Wearability: Which Fits Your Wrist?

• 26331 & 26240 (41mm): Both share the classic Royal Oak 41mm case diameter and integrated bracelet. The 26331 is slightly thinner (~11mm) than the 26240 (~12.4mm) due to movement differences. These fit most wrist sizes comfortably and slip under a shirt cuff easily.
• 26420 (43mm): This is the Offshore – larger, chunkier, and more aggressive. With a 43mm diameter and 15.3mm thickness, it demands a larger wrist and makes a bold statement. It typically comes on a rubber strap (or leather) rather than a full metal bracelet, giving it a sportier, more casual vibe.

Recommendation:

• Go with 26331 or 26240 for an elegant, all-rounder that works with suits and casual wear.
• Choose 26420 if you have a larger wrist and want a rugged, eye-catching sports watch.

3. Movement & Chronograph Functionality

Model	Movement	Power Reserve	Chronograph Type
26331	Caliber 2385 (based on F.P. 1185)	~40 hours	Standard chronograph (pushers start/stop/reset)
26240	Caliber 4401	~70 hours	飞返计时码表 （无需停止即可重置）
26420	约70小时	约70小时	飞返计时码表 （无需停止即可重置）

这对复制品意味着什么：

• 26331: Uses a reliable 2385 clone movement. The subdial layout is classic (3-6-9) and the thickness is well-controlled.
• 26240: The 4401 clone movement is a significant upgrade. It offers a longer power reserve and the flyback function (instant reset). The 50th anniversary version also features a special rotor engraving.
• 26420: Equipped with the 4404 flyback movement, similar to the 26240 but built for the larger Offshore case.

4. Dial & Design Details

26331 – The Classic

• AP logo: Located at 12 o’clock
• Date window: At 4:30 position
• Bracelet: Integrated steel bracelet with full brushing
• Colors: Blue, black, white (panda), grey, rose gold variations

26240 – The 50th Anniversary Modern

• Subdial layout: Same 3-6-9 layout as 26331, but the subdials are slightly larger and more recessed
• AP logo: Applied at 12 o’clock, but the “AUTOMATIC” text is removed from the dial
• Date window: At 4:30 position, but with a matching colored date wheel
• 50th Anniversary rotor: Visible through caseback with special engraving
• Quick release system: Bracelet features quick release for easy strap swaps
• Colors: Blue, black, white (panda), green, grey

26420 – The Offshore

• Subdial layout: 3-6-9 but with larger, more sporty subdial rings
• Bezel: Ceramic bezel with engraved tachymeter scale (unlike the steel bezel on 26331/26240)

5. Bracelet & Strap: Steel vs Rubber

Model	Bracelet/Strap	System
26331	Integrated steel bracelet	Screw links (no quick release)
26240	Integrated steel bracelet	Quick release (easy swap to rubber)
26420	Rubber strap (or leather)	Quick release (standard on Offshore)

Takeaway:
If versatility is key, the 26240 gives you the best of both worlds – a classic steel bracelet that can be swapped for a rubber strap in seconds. The 26420 comes stock on rubber, making it a dedicated sports piece.

6. Factory Recommendations for Super Clones

Model	Top Factory	Why Choose It
26331	APS工厂	The go-to for 26331. Excellent dial texture, correct case thickness (~11mm), and reliable 2385 movement. Panda dial version is highly popular.
26240	APS Factory	Currently the best 26240 replica. Features the 4401 flyback movement, 70-hour power reserve, and accurate 50th anniversary rotor. Quick release bracelet works flawlessly.

  You have a larger wrist and want a bold, sporty watch that stands out. The ceramic bezel, rubber strap, and Offshore DNA give it a completely different personality from the standard Royal Oak.
