The most persuasive detail on a daily diver may be its clasp. You notice whether the bracelet fits every time your wrist changes size through the day, while a spectacular depth rating can remain an abstract number for years. The Christopher Ward C60 Trident Pro 300 puts enough attention into those ordinary details to deserve a serious look.
This guide concerns the blue 40 mm model on the Bader bracelet, reference C60-40ADA31S0BB1-B0. It combines a relatively slim case with a ceramic timing bezel and an adjustable bracelet. The resulting argument is practical: buy it because the complete package suits daily use, rather than merely because it offers a familiar diver silhouette from a smaller brand.

The Pro 300 was developed around everyday priorities
Christopher Ward’s account of the Pro 300’s development describes a response to requests from its independent owners’ forum. The company wanted to retain the Trident identity while reducing the bulk associated with its Pro 600. The new model also reorganised the dial, placing the twin-flags logo at twelve and the date at six, and adopted a two-part bezel arrangement. That background explains the watch better than a borrowed naval adventure would. Its defining historical moment was a discussion about what enthusiasts wanted to wear more often. The current reference continues that approach through a compact profile and bracelet features that address normal ownership, making a practical refinement the central part of its story.
Why the 40 mm proportions matter
The 11.3 mm thickness is the dimension to notice alongside the diameter. It gives the C60 a credible place on a shortlist where larger divers have felt unnecessarily tall. The 47.45 mm lug-to-lug span is still important, since a moderate diameter cannot by itself tell you where the case ends will sit.
With the bracelet included, the listed weight is 160 g. The watch is therefore slim by design without pretending to be weightless. If you enjoy the substance of a steel bracelet but want less case height, that is a useful combination. If the main goal is to forget there is anything on your wrist, a light resin or titanium watch presents a different solution.
The blue dial and matching bezel keep the colour scheme coherent. A fixed steel ring inside the rotating bezel gives the face another boundary, making the architecture more detailed than a simple black ring around a dial. That detail is a reason to study the watch closely, rather than assuming every modern diver offers the same appearance.
The Bader bracelet earns its place
The ratcheting micro-adjustment lets you alter fit without treating every change as a full bracelet-resizing job. Screw links handle the basic length, while quick-release attachment makes changing to a compatible strap straightforward. The owner’s handbook explains the controls and attachment system.
These are useful features for someone who intends to leave the bracelet fitted most of the time. A watch can have attractive dimensions and still become irritating if it is always slightly too loose or too tight. The C60 gives you more ways to address that everyday problem.
The choice of bracelet matters when browsing listings. This is the Bader configuration, rather than the dressier-looking Consort option. Compare the actual clasp and included bracelet before using a headline price to decide which offer is better.
The movement is familiar, the reserve is modest
The Sellita SW200-1 offers a conventional automatic three-hand-and-date experience. Its 38-hour reserve is sufficient for an overnight rest, but it will not reliably bridge a full weekend starting on Friday evening. If you rotate watches frequently, expect more setting than with an 80-hour model.
That is a tradeoff to understand, rather than a reason to dismiss the watch. The visible movement, stopping seconds and straightforward date display all suit an owner who enjoys interacting with a mechanical watch. The more decisive question is whether daily fit matters more to you than the longest possible time off the wrist.
A credible alternative to an Oris?
The Oris Aquis Date 01 733 7792 4154-07 8 19 05P demonstrates why a model-specific comparison is better than ranking whole brands. That 36.5 mm watch also has a ceramic timing ring and a 300 m rating, but offers a smaller case diameter and a different bracelet silhouette. Its current listed reserve is 41 hours.
The Oris is worth trying if the C60 still occupies too much wrist. The Ward deserves attention when you want the documented 40 mm proportions and Bader adjustment system. The differences are tangible enough to guide a purchase without declaring a winner in unmeasured finishing quality.
Who should put it first?
Prioritise the C60 if you want a mechanical diver that will spend most of its life doing ordinary jobs, and you value fit adjustment and moderate height. The international product page showed a late-September 2026 preorder at the source check, so confirm the current UK delivery option before planning around an occasion.
Choose another model if long reserve, particularly low weight or a smaller face is the main requirement. The Trident’s strongest argument is the thoughtful combination of familiar features. It succeeds as a buying proposition when those details solve problems you actually encounter.
