Master Professional Blue (Engraved) - Piece Unique

Squale's connection to the ocean is a testament to a relentless passion for the underwater world, forged through decades of accompanying the globe's most fearless freediving legends. These timepieces have served as trusted tools for athletes like Vincenzo Ferri, the multi-award-winning Italian freediver whose record includes four European and five World Championships. By standing alongside pioneers like Ferri as they push the limits of human endurance, Squale reinforces an unwavering commitment to performance and reliability in the most extreme conditions imaginable. This reputation as a premier case maker was cemented in the 1960s with the introduction of the "Master" case—a technical marvel that famously pushed water resistance to 600 meters at a time when most watches barely scratched the surface. Today, we honor that heritage with a special edition of the Squale Master Professional that debuted to great acclaim at the Baselworld watch fair. Bridging the gap between professional utility and artistic craftsmanship, this edition focuses on a unique stainless steel execution. Moving beyond the standard finish, the case surface is meticulously engraved with patterns reminiscent of the tide, adding a stunning, tactile layer of artistry to its rugged, deep-sea DNA. Squale Master Professional Blue (Engraved) - Piece Unique With a commanding presence, the case measures 44mm in diameter with a 53.5mm lug-to-lug and a 16mm thickness, staying true to its professional-grade roots. What truly sets this special edition apart, however, is the hand-engraved case—the absolute centerpiece of the watch. To bring this vision to life, Squale collaborated with the renowned Italian master engraver Mario Terzi, whose intricate interpretations of marine life transform the case into a technical masterpiece. Almost every visible surface is covered in Terzi's signature work, featuring patterns reminiscent of rolling ocean waves—a rare, tactile tribute that stands in stark contrast to standard production models. These motifs flow seamlessly across the lugs and down the case sides, softened by a delicate satin finish that gives the steel a sophisticated, custom-crafted feel. To create a striking sense of depth, the caseback remains high-polished; this intentional contrast between the textured "wave" engravings and the mirror-like finish ensures the watch remains visually dynamic from every angle. The Squale Master Professional features a specialized "push-down" safety bezel, a technical hallmark of the 60 ATMOS line that turns freely only when depressed and locks securely the moment it is released to prevent accidental shifts. This bi-directional bezel is finished in a deep maritime blue that perfectly matches the dial, featuring a period-correct Bakelite inlay with steel markers and a Super-LumiNova coated triangle pip for essential low-light visibility. Anchored by a signature Squale-signed screw-down crown, the entire construction is engineered to endure depths of 600 meters (60 ATMOS), offering a perfect blend of vintage material charm and fail-safe mechanical functionality.  "Wave" engravings A single-sided, anti-reflective sapphire crystal protects the dial, offering superior scratch resistance and peak clarity for every adventure. Beneath the crystal, the navy blue sunray dial serves as a stunning backdrop for the sword-style hands and hour markers, all of which are treated with C3 Super-LumiNova for exceptional legibility in the depths. In a nod to Squale's technical ingenuity, a unique date window sits at 12 o'clock with an internal magnifying lens for easy reading, while the true soul of the watch is found at 6 o'clock: a dedicated power reserve display. This functional complication serves as the focal point of the dial, perfectly balancing the maritime aesthetic with a clear view of the mechanical heart beating within. The heart of this special edition is a Swiss-made movement built specifically to Squale's exacting standards. Based
