Squale Master 42mm MASTIBLBL.RAL

The Squale Master Collection MASTIBLBL.RAL Men’s Dive Watch is a remarkable example of Swiss dive watch engineering, embodying the brand’s rich underwater heritage and commitment to professional-grade performance. First introduced in 1959, the Squale Master collection was designed to represent the pinnacle of the brand’s technical achievements in pressure resistance and deep-sea reliability. By the 1960s, the original Master models had already achieved an impressive 100 ATM depth rating, cementing Squale’s reputation among professional divers and underwater pioneers. Today, this modern interpretation continues that legacy with advanced materials and precision Swiss watchmaking, making it an outstanding choice for collectors seeking a high-performance Swiss automatic dive watch.

Created to celebrate Squale’s 65th anniversary, this updated Master model is crafted entirely from Grade 5 titanium, marking the first time Squale has produced a watch using this advanced material throughout the entire case. Titanium offers exceptional durability while remaining significantly lighter than traditional stainless steel, allowing the watch to maintain professional diving strength without compromising comfort on the wrist. The robust construction is complemented by a 4mm-thick sapphire crystal and a helium escape valve, enabling the watch to withstand extreme underwater conditions with an impressive 120 ATM water resistance. With a 42mm case diameter, 15.5mm thickness, and 49mm lug-to-lug length, the watch delivers a strong masculine presence while maintaining excellent wearability.

Designed for maximum underwater readability, the Squale Master features a brushed ceramic bezel with SuperLuminova markers, ensuring clear visibility even in low-light diving environments. The dial showcases a sophisticated three-layer “sandwich” construction, a technique widely appreciated by professional dive watch enthusiasts. The base layer consists of a full disk of SuperLuminova Old Radium, providing powerful luminescence that recalls the vintage look of the original 1960s Squale Masters when tritium was used. A perforated dial sits above this layer, enhancing the glow of the indexes, while applied brushed markers form the final layer, perfectly matching the finish of the hands and titanium case for a cohesive, high-end appearance.

Powering the watch is the reliable Swiss-made Sellita SW200-1 automatic movement in Elaboré grade, operating at 28,800 vibrations per hour (4 Hz) with 26 jewels and offering a 38-hour power reserve. This dependable movement ensures accurate timekeeping and long-term reliability, reflecting the precision engineering expected from a professional Swiss dive watch. The case is finished with a screw-in crown and screw-in caseback, reinforcing water resistance and durability for serious underwater use.

What we love about the Squale Master Collection MASTIBLBL.RAL is how it beautifully combines Squale’s historic dive watch expertise with modern materials and technical innovation. The lightweight yet incredibly strong Grade 5 titanium construction, the impressive 120 ATM water resistance, and the vintage-inspired SuperLuminova sandwich dial make this watch both a professional diving instrument and a collector-worthy timepiece. It perfectly represents Squale’s long-standing reputation for building high-quality Swiss dive watches engineered for extreme underwater performance.
