How do you change the strap on your Swatch collaboration watch?

You can swap your strap in minutes — no watchmaker needed. Every WatchCollab strap ships with spring bars and a fitting tool, and the process is the same on the Omega x Swatch MoonSwatch, the Blancpain x Swatch Scuba Fifty Fathoms and the Audemars Piguet x Swatch Royal Pop. Rest the watch dial-down on a soft cloth, compress the spring bars with the tool to release the old strap, insert the spring bars into the new strap, seat them in the case lugs on both sides, then pull gently to check there is no play.

Technology, performance and sustainability

The Blue Lagoon is the perfect alliance of innovative design, advanced materials and watchmaking performance. Built in a Bioceramic case — an exclusive material of ceramic and bio-sourced plastic — it offers exceptional lightness, high UV and dust resistance, and great tolerance thanks to hypoallergenic properties. To accompany this technological gem, the rubber Blancpain x Swatch straps bring optimal comfort and a bold aesthetic, perfectly suited to daily use as well as sport or water activities. In premium rubber, they combine suppleness, durability and style while respecting the quality standards of Blancpain and Swatch.

Mechanically, the Blue Lagoon integrates the automatic SISTEM51 movement, a real Swatch feat. With just 51 components, it offers an impressive 90-hour power reserve and anti-magnetic protection via the Nivachron alloy. The sapphire case back reveals an original marine illustration of a lagoon and the nudibranch Tambja Mullineri, reinforcing the underwater theme. Eco-commitment is also central: the NATO strap made from recycled fishing nets shows Swatch and Blancpain's shared drive for more responsible, sustainable watchmaking.

Reference dive performance

The Blue Lagoon continues the tradition of exceptional dive watches. Water-resistant to 91 metres (50 fathoms), it has a unidirectional Bioceramic bezel with a dive scale, guaranteeing safety and precision on every immersion, and Grade-A Super-LumiNova on the hands and indices ensures optimal legibility even in the darkest depths.

An emblematic collaboration

The Swatch and Blancpain partnership continues the Swatch Group's landmark collaborations, echoing the worldwide success of the MoonSwatch with Omega. This synergy between Blancpain's heritage and Swatch's accessible innovation celebrates 70 years of the legendary Fifty Fathoms, a pioneering dive watch since 1953.

Ocean models: a revolution in modern watchmaking

A strategic turning point

The Swatch and Blancpain collaboration shook up the watch world, pairing Blancpain's prestigious heritage with Swatch's accessible, innovative approach. This bold partnership shows the industry's ability to evolve, honouring its past while meeting a new generation's expectations. The Bioceramic Scuba Fifty Fathoms collection embodies this modernity through durable materials and ocean-inspired designs. Iconic Antarctic Ocean and Pacific Ocean straps reflect this shared vision: technical, durable, yet stylish watches. This strategic repositioning gives Blancpain reinforced visibility while appealing to a wider audience.

A shared vision: performance, durability and aesthetics

The Scuba Fifty Fathoms collection reflects a perfect harmony of Blancpain and Swatch values. The two brands created five Bioceramic models, each dedicated to an ocean — a celebration of the world's natural heritage and a strong commitment to protecting the seas. The Pacific Ocean and Antarctic Ocean straps, carefully designed, extend this mission with comfort, robustness and environmental awareness. The automatic SISTEM51 movement at each model's heart ensures optimal reliability with 90 hours of reserve and Nivachron anti-magnetic protection.

Built for diving... and beyond

The Blue Lagoon perfectly illustrates modern dive-watch function. Water-resistant to 91 metres, with a unidirectional Bioceramic bezel and Super-LumiNova indices, it guarantees safety and legibility underwater, while its lightness and resistance make it an ideal companion for divers and comfortable for daily wear. But it's more than technical: with its vivid turquoise, sun-brushed dial and eco NATO strap, it's a real fashion accessory. The Antarctic Ocean strap highlights a cool, elegant tone inspired by the South Pole's ice, while the Pacific Ocean strap evokes the depth and serenity of the world's largest ocean.

An enthusiastic response

The reception of the Blue Lagoon exceeded expectations. Fans praised its innovative approach, the inspiring messages engraved on the case back, and its accessible price of around €400. The ability to personalise via interchangeable straps — including the Pacific Ocean and Antarctic Ocean bands — reinforced its appeal to a young, demanding audience.
