The clearest blue ceramic dive watch with a ceramic-led case that we could verify is the Bremont Supermarine Full Ceramic Deep Blue. It is not an all-ceramic watch, though. Its case is mono-block ceramic, but the inner case and bezel are titanium, and the bezel carries a blue ceramic insert. If your priority is the lowest wrist weight, the evidence points to titanium cases with ceramic bezels rather than to the Bremont, and the published weight figures are limited. This guide is a shortlist of four models, not a ranking.
Which blue ceramic dive watch has a lightweight case?
Bremont describes the Supermarine Full Ceramic Deep Blue as a lightweight blue ceramic dive watch rated to 500 m. The product pages reviewed for this guide do not publish a numeric full-watch weight, so we cannot say how it compares on the scale with the titanium models below. The four options that follow are the ones whose manufacturer pages offer enough detail to compare meaningfully.
Bremont Supermarine Full Ceramic Deep Blue
This is the most direct match for a blue ceramic case. Bremont’s US product page describes a mono-block blue ceramic case, and its Hong Kong listing gives a 43 mm case diameter. The same construction carries a titanium inner case and bezel, with a blue ceramic insert in the bezel. The manufacturer rates the watch to 500 m and lists a 56-hour power reserve on its US page.
Bremont states that this edition is limited to 250 pieces. That is the manufacturer’s edition figure. The pages we reviewed do not confirm how many remain, so check current stock with Bremont or an authorised retailer before planning a purchase, and confirm the strap or bracelet configuration you want, since it varies by listing.

Aldo Kane, identified on Bremont’s product page as a Bremont Ambassador, writes: “Having already tested the Full Ceramic in the jungle, I knew how capable the Supermarine platform was. Iceland presented a completely different challenge, taking us from extreme cold-water dives to exposed glacier climbs and high into the mountains in some fairly extreme weather.” This is his personal account, printed by the brand. It is not independent verification of the specifications.
Certina DS Action Diver 38mm Titanium
The Certina DS Action Diver 38mm Titanium (reference C048.807.44.041.00) is a blue automatic model with a grade 2 titanium case and a scratch-resistant ceramic bezel. Certina rates it to 300 m. Its 38 mm case makes it the smallest of the four options. The UK product page lists a price of £925; prices in other regions may differ, so check your local Certina site.
Rank #2
- LIGHT-POWERED QUARTZ - Converts ordinary light into stored energy through an ML2016 rechargeable cell. A full charge keeps the watch running for up to 6 months in darkness, with no charging cable needed.
- 200M WATER RESISTANCE - Rated to 200 meters/660 feet for swimming, snorkeling and water sports. Always screw the crown fully closed before water exposure; never adjust it underwater. Not for showering, bathing or sauna use.
- SCREW-DOWN CROWN - The threaded crown and double-seal structure help support water resistance and prevent accidental time changes. Unscrew and pull to set the time, then press and turn clockwise until secure.
- BOLD, EASY-READ DIAL - Oversized hands, raised hour markers and strong contrast make the time easy to read at a glance. The textured grid dial and minute-marked bezel create a rugged, ocean-inspired look.
- ACTIVE-WEAR COMFORT - The flexible textured strap stays comfortable and secure through daily use and water activities. After saltwater exposure, rinse the watch with fresh water and dry it thoroughly.
Baltic Aquascaphe Titanium Blue
Baltic lists a case weight of 55 g for the Aquascaphe Titanium Blue, the only full-watch weight figure among these models. The case is titanium and the bezel is described as scratch-resistant ceramic. The product page does not state a water-resistance rating in the material we reviewed, so do not assume one from the other models in this guide. Because the 55 g figure refers to the case, read it as a case weight rather than a complete wristwatch weight with bracelet and movement included.
Panerai Submersible GMT PAM01495
This Panerai is included as an example of a blue ceramic detail on a titanium watch, not as a lightweight-case recommendation. Its bezel is titanium with a blue matte ceramic disc, and the product name gives a 47 mm size. The Canadian product page we reviewed did not establish the watch’s weight or water-resistance rating.

Is a titanium dive watch with a ceramic bezel lighter than an all-ceramic watch?
The available evidence does not establish this. Titanium is a lighter metal than steel, and the Baltic’s 55 g case figure shows what a titanium case can weigh. But none of the manufacturer pages gives a comparable case weight for the Bremont, so we cannot say the Bremont is heavier or lighter than the titanium models. Treat any claim that a ceramic-cased watch is lighter as unsupported until you see published weights for the specific references you are comparing.

What to compare before you buy
Because published weights are sparse, build your own comparison from the same set of details for each model:
Rank #4
- Refined Design & Upgraded Movement: Compared to the WD5512 V2 PT, the WD5512B features a reduced inner rehaut slope for a cleaner, flatter dial appearance. Powered by the reliable ST2130 high-beat automatic movement (28,800 bph) for smoother sweeping and better accuracy.
- Premium Materials: Crafted from solid 316L stainless steel with a sunburst blue or enamel black dial. Features a sapphire crystal with AR coating and a 2.5x date window convex magnifier for easy date reading.
- Pro-Grade Bezel & Luminous: Unidirectional 120-click chronograph bezel with a scratch-resistant ceramic top ring and a luminous marker at 12 o’clock. Filled with BGW-9 blue light luminous on hands and markers for superior low-light visibility.
- Built For Water - Solid Diver Construction: Compact 40mm case (48mm lug-to-lug) with an ultra-slim 11.8mm profile. Both crown and case back are screw-down design, delivering reliable water resistance for swimming, snorkeling, and everyday wet conditions.

- How much of the case and bezel is ceramic, and whether the case itself is ceramic or only the bezel insert
- Case weight, if the manufacturer publishes it, and whether the figure includes the bracelet or strap
- Case diameter and lug-to-lug fit on your wrist
- Water-resistance rating, which is the manufacturer’s specification
- Strap or bracelet configuration, since the same reference can be sold on different straps
- The price in your region, not only the list price on a single country’s site
How much to trust the figures
Every figure in this guide comes from manufacturer product pages: the 500 m and 250-piece limit from Bremont, the 300 m and £925 price from Certina, and the 55 g case weight from Baltic. We did not test any of these watches, so the water-resistance ratings and weights are the brands’ own claims. The product pages reviewed do not state when they were published, and we found no independent study that measures these models’ weights or depth ratings.
For the Bremont, the most useful check before buying is to confirm the edition and stock position directly with the brand, because the 250-piece figure describes how the edition was made, not what is left to buy.

Our shortlist
If you want a blue ceramic case specifically, the Bremont Supermarine Full Ceramic Deep Blue is the model to look at first, with the mixed-material construction described above. If your main concern is keeping weight down while keeping a ceramic bezel, the Certina DS Action Diver 38mm Titanium is the smaller option, and the Baltic Aquascaphe Titanium Blue is the one with a published case weight. The Panerai is useful as a reference for how a blue ceramic detail looks on a titanium watch.
