The Rado Captain Cook collection has grown with two compelling new additions that bring oceanic colorways to the Swiss brand’s popular tool watch line. These latest additions feature gradient dials and ceramic bezels and introduce a fresh 39mm case size, which bridges the gap between the existing 37mm and 42mm options.
Fresh colorways meet familiar form
Both new models maintain the Captain Cook’s fundamental design language, exploring different moods of ocean adventure. The first model has a light blue-to-white gradient dial and a light blue ceramic bezel insert, reportedly the first time Rado has produced this shade. This combination evokes the appearance of shallow tropical waters under clear skies and is sure to appeal to those who enjoy leisurely aquatic activities.
The second model takes a more dramatic approach with a black-to-turquoise gradient dial and a matching black ceramic bezel. This colorway suggests deeper waters and more serious maritime activities, such as sailing expeditions and cold-water adventures. Both variants maintain the collection’s sporting character while appealing to different aesthetic preferences.
Technical specifications and movement
Both watches house the Rado caliber R763, an automatic movement that delivers 80 hours of power reserve. The movement features an antimagnetic Nivachron hairspring that provides enhanced resistance to magnetic fields, a practical consideration for modern wearers surrounded by electronic devices. The caliber operates with 25 jewels and includes adjustment across five positions for improved timekeeping accuracy.
The movement displays time with three hands and a date window positioned at 3 o’clock. While some might prefer a more complex display, the straightforward layout aligns with the original Captain Cook’s minimalist design from 1962. Here, function follows form, prioritizing legibility and reliability over complications.

Case construction and water resistance
Both models have polished stainless steel cases that measure 39.0 x 45.5 x 12.0 mm. The 39mm diameter strikes a balance, accommodating those who find the 37mm too small and the 42mm too large. The 12 mm height keeps the profile reasonable for daily wear while comfortably housing the automatic movement.
With water resistance reaching 300 meters (1,000 feet), these watches are suitable for recreational diving and water sports. The screw-down crown features an embossed anchor logo, and the caseback displays three relief seahorses—both nods to the maritime heritage. A domed sapphire crystal with anti-reflective coating on both sides protects the dial.
The bezel design and functionality
The unidirectional rotating bezels serve practical timing functions and add visual interest. The light blue model features silver-toned numerals and markers, and the black version uses white Super-LumiNova for enhanced visibility in low-light conditions. Both bezels utilize Rado’s ceramic expertise, delivering scratch resistance and color stability.
The ceramic inserts showcase Rado’s material science capabilities; the brand is often called the “Master of Materials” for its innovative use of advanced ceramics. These inserts are more durable than painted or anodized alternatives, which is an important consideration for watches intended for active use.
Dial details and legibility
Applied rhodium-colored indices with white Super-LumiNova ensure readability across various lighting conditions. The luminous material glows white under bright light and shifts to blue in darker environments, providing consistent visibility underwater or during evening activities. The hands receive the same treatment to maintain visual coherence.
Both dials feature a mobile anchor symbol on a ruby background, connecting to Captain Cook’s nautical heritage. The Rado and Captain Cook logos appear in contrasting colors—light gray on the blue model and white on the black version—ensuring brand recognition without overwhelming the design.
Bracelet and wearing experience
The stainless steel bracelet has a rice grain pattern that creates visual texture while maintaining comfort. Polished and brushed surfaces provide contrast and prevent the bracelet from appearing uniform. Rado’s EasyClip system allows for quick adjustments; however, the specific details of the mechanism remain unclear based on the available information.
The triple-folding deployant clasp should provide security during active wear; however, sizing adjustments may require professional attention, depending on the specific link design. The 39 mm case size works well with the proportioned bracelet, avoiding the occasional mismatch between case and bracelet dimensions.
Positioning and market appeal
These new Captain Cook models target different segments within the diving watch market. The light blue version appeals to those seeking a casual, vacation-ready timepiece, while the black and turquoise model attracts buyers wanting a serious-looking tool watch. Both maintain the collection’s affordable pricing compared to other luxury diving watches.
The 39mm size addresses a common complaint about modern watch proportions by offering a size that works well on various wrists. This practical feature could broaden the collection’s appeal beyond traditional diving watch enthusiasts to include individuals seeking well-crafted sports watches for everyday wear.
Rado’s latest Captain Cook models successfully expand the collection’s appeal through thoughtful color choices and practical sizing. The gradient dials provide visual interest without compromising legibility, and the ceramic bezels showcase the brand’s material expertise. The 39 mm case size fills a useful gap in the lineup and could attract new customers who found previous sizes unsuitable.
