Corgeut CG3002 – 40mm Automatic Watch | NH35 | Sapphire Crystal
There is a reason this particular style of sports watch has become so popular; a rotating bezel, large luminous markers, magnified date and solid steel case provide much of the practicality associated with a dive watch, while the more polished finishing and curved bezel design make it considerably easier to wear with smarter clothing. The Corgeut CG3002 takes that familiar formula and brings it into a much more accessible price range.
The case is approximately 40mm across, which puts the CG3002 in a particularly versatile position for a modern sports watch; it has enough presence to suit the broad bezel and substantial hour markers without moving into the genuinely oversized territory of many 43mm and 44mm divers. At around 13.5mm thick, it is still a fairly substantial watch, which is to be expected from an automatic sports watch with a rotating bezel and 100m water resistance, but buyers looking for something particularly slim beneath a shirt cuff may be better served by a simpler dress or everyday watch.
Inside is the Japanese TMI NH35 automatic movement. Automatic means that the watch winds itself through the movement of your wrist, although it can also be manually wound through the crown after it has stopped. You also get hacking seconds, which stops the seconds hand while setting the time, and a quick-set date. The NH35 uses 24 jewels and runs at 21,600 vibrations per hour, or six beats per second which produces the familiar mechanical sweep of the seconds hand rather than the individual once-per-second tick associated with most quartz watches. The power reserve is approximately 41 hours when fully wound, meaning the watch should comfortably continue running overnight and into the following day after being removed. TMI's standard accuracy specification is approximately -20 to +40 seconds per day, so it should not be confused with quartz precision, but this is perfectly normal for an affordable mechanical movement. The NH35 has become one of the most widely used movements in affordable automatic watches, and there is good reason for that; it is not particularly glamorous or complicated, but it is established, straightforward and widely understood. For someone buying their first automatic watch, that sort of proven mechanical foundation makes considerably more sense than using an obscure movement simply to make the specification sound more unusual. At three o'clock is a date window with a magnifying lens above it which makes the date considerably easier to read at a glance and reinforces the more luxurious sports-watch appearance of the design.
Above the dial itself is sapphire crystal which is considerably more resistant to everyday surface scratching than conventional mineral glass and is one of the specifications I particularly like seeing on a watch intended for regular use. Surrounding the crystal is a ceramic bezel insert with a raised timing scale. Ceramic is considerably more resistant to scratching and fading than the aluminium inserts traditionally used on many sports watches, helping the bezel retain its appearance through regular wear. The bezel itself rotates through 120 clicks which gives it a genuine timing function rather than simply making it a decorative part of the case. Aligning the zero marker with the minute hand allows you to keep track of elapsed time for anything from exercise and cooking to parking. It is worth making a distinction here, though. Despite its obvious aquatic styling, the CG3002 is better thought of as a sports watch with dive-watch influences than as a dedicated professional diver.
Legibility remains appropriately strong; large circular and baton hour markers sit against the dial, with luminous material applied to both the hands and indices. This makes the watch much easier to read once the surrounding light disappears and suits the sporting character considerably better than delicate dress-watch hands would. The different colour combinations change the personality of the CG3002 quite dramatically. The silver stainless-steel version is the most restrained and versatile, keeping the overall appearance relatively monochromatic and allowing the black dial to provide most of the contrast. The gold-tone versions are far more assertive, combining a warm case finish with a striking black dial, dark bezel and rubber strap creates something much more noticeable on the wrist.
Strap choice makes another significant difference; the stainless-steel bracelet gives the silver version a heavier and more traditional sports-watch feel, while the rubber variant gives a more relaxed feel and is more obviously suited to casual wear. The 20mm lug width is particularly useful as it is one of the most common strap sizes available. Even if the watch is supplied on steel, changing to a rubber, leather or fabric strap later should be straightforward and can alter the character considerably.
Water resistance is rated to 100m, or 10 bar which gives the CG3002 considerably more flexibility around water than a typical 30m or 50m dress watch and makes ordinary swimming perfectly reasonable, provided the crown is properly secured.
The CG3002 provides much of the visual presence of a luxury nautical sports watch without demanding that the owner treat it like something precious. Sapphire crystal and a ceramic bezel add useful everyday durability, while the NH35 provides a mechanical movement that is well established and straightforward to live with. The 40mm dimensions also make it more versatile than many affordable automatic sports watches as it is large enough to feel substantial, but not so wide that it immediately dominates the wrist.
For someone looking for a first automatic sports watch that can cover weekends, holidays, swimming and ordinary everyday wear while still looking smart enough for more formal situations, the CG3002 offers a strong combination of practicality and mechanical character. The originality may be limited, but the basic watch underneath the familiar design gets a lot right.

Worth knowing:
The design is very clearly inspired by the Rolex Yacht-Master. The bezel, dial layout, magnified date and case design all follow that watch closely, which may be either a disadvantage or a major part of the appeal depending on what you are looking for.
Water resistance is rated to 100m/10 bar, making ordinary swimming reasonable.
The silver stainless-steel bracelet and gold-tone rubber-strap versions can feel quite different on the wrist despite sharing the same basic case. The steel version is more substantial and versatile, while the rubber option is lighter and more overtly sporting.
