Squale Master Review: A Modern Dive Watch with Vintage Soul
The Squale Master is a watch that understands its lineage. Born from a brand that supplied dive watches to military and professional divers in the 1960s and 70s, the Master collection distills that heritage into a contemporary package. The reference MASTIBKBK.T120, with its black dial and black bezel, is perhaps the most archetypal of the line. It is a tool watch that refuses to shout, yet its every detail—from the cushion-shaped case to the domed sapphire crystal—whispers of a time when dive watches were built for function, not fashion. For the young collector seeking a daily wearer with genuine provenance, the Squale Master is a compelling proposition.
This review examines the Master through the lens of a horology enthusiast who values movement architecture, finishing, and real-world wearability. We will dissect the case, the movement, the dial, and the bracelet, and then place the watch within the broader context of Squale’s history and the current market. The goal is to provide a thorough, honest assessment that helps you decide whether this watch deserves a place in your collection.
Manufacture History
Squale was founded in 1959 by Charles von Büren in Neuchâtel, Switzerland, but the brand is now based in Italy. It originally manufactured cases for other watch brands before launching its own line of dive watches. The Master collection revives the iconic 1521 and 1545 designs, blending vintage aesthetics with modern reliability. Squale’s history is deeply intertwined with the golden age of diving, and the Master pays homage to that era without being a mere reissue.
Movement
At the heart of the Squale Master beats the Sellita SW200-1, a Swiss automatic movement that is a direct descendant of the ETA 2824-2. It operates at 28,800 vibrations per hour, has 26 jewels, and offers a power reserve of approximately 38 hours. The movement is decorated with circular Geneva stripes on the rotor and perlage on the bridges, visible through the exhibition caseback. While not COSC-certified, the SW200-1 is known for its robustness and ease of service. In practice, the movement runs within -10/+20 seconds per day, but many examples perform better. The date changes crisply at midnight, and the winding feel is smooth with a slight ratcheting sound.

Wrist Feel
On the wrist, the Squale Master is a study in balance. The 40mm case diameter and 48mm lug-to-lug length ensure it sits comfortably on a wide range of wrist sizes—from 6.5 to 7.5 inches. The cushion-shaped case, with its brushed and polished surfaces, catches light without being flashy. The domed sapphire crystal adds a subtle vintage curvature that reduces glare and enhances legibility. The watch is 12.5mm thick, which is moderate for a dive watch; it slides under a shirt cuff with ease.
The included rubber strap is supple and well-proportioned, tapering from 20mm to 18mm at the buckle. It does not pull hair and dries quickly after a swim. The pin buckle is signed with the Squale logo and feels secure. The overall weight is 85 grams on the rubber strap, making it light enough for all-day wear. The crown, signed with the Squale shark, is easy to grip and screws down smoothly. The bezel action is crisp with 120 clicks, and the unidirectional rotation has no backplay. The Master feels like a tool watch that was designed by someone who actually wears one.
Accuracy
In real-world testing over two weeks, the Squale Master (ref. MASTIBKBK.T120) ran consistently at +6 seconds per day when worn for 10–12 hours daily. When left dial-up overnight, it gained an additional +2 seconds. This is within the expected range for a Sellita SW200-1 movement that has not been regulated to COSC standards. The movement is stable across different positions, and the amplitude remained healthy at 290° after 24 hours. For a daily wearer, this level of accuracy is more than adequate. If you require chronometer-level precision, a simple regulation by a watchmaker can bring it to within +2 seconds per day.
Occasions
The Squale Master is a versatile tool watch. It excels in sport and daily wear, whether you’re swimming, hiking, or commuting. Its 300m water resistance makes it suitable for recreational diving. It is not a formal dress watch, but its understated design allows it to pair with casual blazers or smart-casual attire. For travel, the robust construction and reliable movement make it a trustworthy companion.
Wrist Presence
3.5/5 – The Squale Master is understated but purposeful. It does not scream for attention, but its vintage-inspired cushion case and domed crystal give it a distinct personality. On a rubber strap, it blends into casual and sporty settings. It is not a dress watch, but it can accompany a blazer if the occasion is relaxed.

Investment Value

The market is stable; the watch does not appreciate significantly but holds its value well. It is not a limited edition, so don’t expect auction fireworks. Buy it to wear and enjoy.
Service Interval
Squale recommends a service every 5 years. A full service for the Sellita SW200-1 costs approximately $350 at an independent watchmaker. Parts are readily available, and the movement is easy to work on. Authorized service is not required, but using a reputable watchmaker is advised.
Pros and Cons
Pros: Authentic dive watch heritage, comfortable 40mm case, reliable Sellita movement, excellent legibility and lume, versatile rubber strap.
Cons: Not COSC-certified, bracelet option adds cost, crown can be small for gloved hands, no quick-adjust clasp on rubber strap.
Final Verdict

It offers a genuine alternative to the ubiquitous Submariner homages, with a distinct Italian-Swiss character. For the collector who values provenance, wearability, and honest construction, the Master is a worthy addition to any rotation.
