ID Geneva’s Circular C-SDG is a sustainable watch masterpiece

ID Geneva introduces the sustainable Circular C-SDG limited edition

ID GENÈVE X SDG — ID GENÈVE

ID Geneva has made a winning case for contemporary haute horology with the release of their Circular C-SDG Limited Edition, a timepiece unveiling as intellectually compelling as it is visually stunning. The Circular C-SDG is a wearable manifesto for sustainability, representing a bold march towards a more conscious future for luxury watchmaking. The watch’s sleek 42mm case is masterfully crafted from a single block of recycled Lucent steel, a proprietary alloy that offers a brilliant luster surpassing that of conventional stainless steel. Its monolithic silhouette is punctuated by an openworked dial that reveals the intricate mechanics lying within, framed by a unidirectional bezel crafted from 100% recycled 18k rose gold and embellished with a mesmerizing blue ceramic insert.

The Circular C-SDG’s movement speaks to elevated sophistication

Beneath its architecturally dynamic exterior lies the center of this horological revolution: the Caliber 1040. This stellar automatic movement is a masterpiece of sustainable engineering, utilizing recycled gold for its rotor and bridges, and lubricants taken from renewable carbon. The openworked dial includes circular-grained bridges and bevelled edges, all conforming to the highest standards of fine watchmaking. This commitment aligns with the brand’s innovative ‘circular’ economy model, where ID Geneva offers to buy back the watch’s materials at the end of its life, ensuring they are perpetually recycled into new components. This is watchmaking with a conscience, proving that luxury can be fabulous and eco-conscious at the same time.

ID Geneva directs a visionary path for the future of luxury

With the Circular C-SDG, ID Geneva has created a luxury timepiece that challenges the status quo, offering the discerning collector an opportunity to possess a work of art that aligns with a progressive ethos. For the connoisseur who values impeccable craftsmanship, avant-garde design, and a legacy of environmental advocacy, this limited edition stands as a profoundly significant and desirable achievement.

Swatch’s new gold MoonSwatch is priced like it’s 1969

The Mission to the Moon 1969 packs 11 grams of real 18K gold — priced at the 1969 gold rate.

Wristwatch, Arm, Body Part

Guess what? It's another MoonSwatch — but this isn't just another colorway. The new drop from the Switzerland-based watchmaker, the MoonSwatch Mission to the Moon 1969, is the first to use real gold across the dial, hands, crown, and pushers.

The watch marks the anniversary of the Apollo 11 landing on July 21, 1969.

Breitling’s new Top Time is a wearable tribute to the Aston Martin DB5

The new watches rep the iconic Bond car right down to subdials shaped like its dashboard gauges.

Car, Watch, Man

Breitling just released a trio of heaters: the Top Time B01 Chronograph 41 Tribute to Aston Martin DB5, a three-edition collaboration with the British carmaker. The connection between the Swiss watchmaker and the British car company runs back to 1965, when a Top Time ref. 2002 appeared on Sean Connery's wrist in Thunderball, worn alongside the DB5 — the first Q-modified watch in the Bond series. It's a nice bit of trivia that the DB5 and that Top Time shared the screen in the same film, and both went on to outlive the movie by decades.

The car cues go deeper than the "squircle" gauge-shaped subdials: a wooden inner ring nods to the DB5's steering wheel, and each edition rides on a hand-colored gradient calfskin strap meant to read like automotive upholstery. All three run on Breitling's in-house Manufacture Caliber 01, a COSC-certified automatic chronograph with a 70-hour power reserve, visible through a sapphire caseback and finished with an Aston Martin-engraved rotor. The case measures 41mm. The editions are divvied up by material and rarity. Stainless steel with a silver dial is limited to 1,022 pieces and sticks closest to the original ref. 2002, while steel with a platinum bezel and black lacquered dial drops to 315 pieces.

Look to the sky for these space themed watches

These 5 space themed watches will have you seeing stars

Accessories, Strap, Wristwatch

It was the 1960s. We were in the middle of a Cold War with Russia, and instead of escalating to an actual war with bullets and bombs, we took the conflict to the sky. We created a war of economics, science, and morale in a race to the sky to be the first nation to reach the moon. While the race picked up throughout the decade, it came down to the wire before the USA won the race by landing on the moon (if you believe that sort of thing and don't believe Stanley Kubrick directed the greatest ruse of all time). In any case, no race can be run without a good timekeeper. And watches were a must-have for all involved. Ever since, chronophiles like me have been obsessed with space-themed watches and, in particular, moon mission watches.

That is why I happened to have this list in my head. Five watches that bring the space race and the great beyond to the forefront of thinking to build a collection that is out of this world.
