Choose the Rado Captain Cook if you want a conventional external rotating bezel and, in the cited 39 mm reference, an 80-hour power reserve. Choose the Longines Legend Diver if you prefer its twin-crown design and protected internal rotating bezel. The cited steel examples share a stated 30 bar (300 m) water-resistance rating, so the practical decision is less about headline depth ratings and more about bezel style, exact configuration and fit.
How the bezel changes the experience
Rado Captain Cook: the familiar external bezel
The Captain Cook uses an external turning bezel. In the 39 mm R32223213, the bezel has a high-tech ceramic insert, set against a steel case and gradient dial. Its arrangement will feel familiar to anyone who prefers a conventional dive-watch bezel that can be operated from the outside. Rado’s R32223213 specifications.

Longines Legend Diver: an internal bezel and second crown
The Legend Diver puts its turning diving flange inside the case; a second crown operates it. Longines says this position protects the bezel from accidental manipulation and shocks that could alter its setting. That is the brand’s explanation of the design, not an independent comparative test. Longines’ L3.764.4.06.9 specifications and Legend Diver collection page.
The choice is straightforward: pick the Captain Cook if you want the exposed, conventional layout; pick the Legend Diver if you want the bezel integrated beneath the crystal and are comfortable operating it with the additional crown.

What the exact 39 mm references offer
Collection names cover multiple sizes and configurations. These are the specifications for the cited steel references, not promises that every Captain Cook or Legend Diver has the same details.
| Specification | Rado Captain Cook R32223213 | Longines Legend Diver L3.764.4.06.9 |
|---|---|---|
| Case and appearance | 39 mm steel case; gradient dial; ceramic bezel insert | 39 mm steel case; green dial; supplied with a rubber strap |
| Movement and reserve | Automatic R763 calibre; 80-hour power reserve | Automatic; up to 72-hour power reserve; 25,200 vibrations per hour |
| Water resistance | 30 bar (300 m), as stated by Rado | 30 bar, as stated by Longines |
| Other listed details | Date, Nivachron hairspring and sapphire crystal | Monocrystalline silicon balance-spring, screw-in crown and sapphire crystal with anti-reflective coating on both sides |
The eight-hour reserve difference applies to these references: Rado lists 80 hours for the R32223213, while Longines lists up to 72 hours for the L3.764.4.06.9. Those are manufacturer specifications, not results from an independent movement test. Sources: Rado and Longines.

Case size, fit and configuration
Both collections include 39 mm and 42 mm options. Rado also describes a 37 mm Captain Cook variant on its 39 mm product page. For a 42 mm comparison, Rado lists the R32105203, while Longines lists 42 mm models in the Legend Diver collection. A case diameter does not establish which watch will fit a particular wrist better; the available specifications here do not provide a same-method lug-to-lug comparison or hands-on fit assessment.

Water resistance: equal on paper, not a condition guarantee
The cited 39 mm references are both rated by their manufacturers to 30 bar; Rado also lists 30 bar for the 42 mm R32105203. This is a specification, not evidence of independent testing for this comparison, and it cannot establish the present water resistance of a used watch or one whose seals have not been maintained. For a watch intended for water use, condition and appropriate servicing matter alongside the rating.
Longines recommends rinsing its watch in fresh water after contact with seawater and having water resistance checked once a year by an approved Longines Service Centre. This is Longines guidance; it should not be read as a Rado-specific service instruction. Longines user manual.

Which one should you choose?
Choose the Captain Cook if…
- You prefer an external, conventional rotating bezel.
- The cited 39 mm R32223213 configuration appeals to you: steel, a gradient dial and a ceramic bezel insert.
- An 80-hour reserve is useful to you, based on Rado’s specification for that reference.
- You want to compare several Captain Cook sizes, including listed 37 mm, 39 mm and 42 mm options.
Choose the Legend Diver if…
- You prefer an internal bezel operated by a second crown and the twin-crown appearance.
- You want the specific cited 39 mm version with a green dial and rubber strap.
- A reserve of up to 72 hours meets your needs.
- You value Longines’ stated rationale for the internal bezel: its position inside the case is intended to protect it from accidental manipulation and shocks.
There is no universal winner in the published specifications. Decide first which bezel arrangement you will enjoy using, then compare the exact size and configuration available to you. The cited examples match on stated water resistance, while their designs and reference-specific reserves differ.
Brand-stated heritage
Rado says the Captain Cook was inspired by its 1962 original. Longines dates the Legend Diver design to 1959 and describes the original internal-bezel, twin-crown concept on its collection page. These are the brands’ accounts of their designs’ heritage. Rado Captain Cook page and Longines Legend Diver collection.
