Tribute to adventure
The Seastrong Diver Extreme Automatic, limited edition of 150 pieces, celebrates the Arkea Ultim Challenge. Its 41x42.50 mm stainless steel case, water-resistant to 200m, houses the AL-525 automatic caliber. The silver dial, decorated with the Arkea logo, and the blue bezel recall the marine world.


Performance and robustness at the service of exploration
This diving watch is designed for adventure. Its automatic movement, equipped with 26 jewels, ensures reliable precision. The anti-reflective sapphire crystal protects the dial, while the screw-down crown and caseback guarantee water resistance. The navy blue rubber strap offers comfort and safety during underwater explorations.
A symbol of passion and commitment
The Seastrong Diver Extreme Automatic Arkea is more than a watch, it is a symbol of passion for the sea and commitment to challenges. The caseback engraved with the "Arkea Ultim Challenge – Brest" logo and the words "1 OUT OF 150" bear witness to its exclusive and commemorative character.
