The Super Sea Wolf Pro-Diver is the most overtly tool-focused expression of that lineage, and this ZO3552 is the blacked-out, no-nonsense version: a 42 mm stainless steel case, a fully graduated ceramic bezel insert with luminous markers, and a black sunray dial read through sapphire.\u003c\/p\u003e\n\u003cp\u003eWhat elevates it above the crowded mid-size-diver field is what sits inside and what stands behind it. The case holds a Swiss-made Sellita SW200-1 automatic, and the watch is COSC and ISO certified to 30 ATM — a chronometer-grade movement and an ISO-rated dive case at a price point where neither is a given.\u003c\/p\u003e\n\u003cp\u003eThis particular example has not been worn. BST's inspection found it brand new with the factory protective stickers still in place, with no wear to speak of. It arrives as Box, Papers, and Cards, on its full-length seven-link bracelet, currently sized to fit an approximately 8-inch wrist.\u003c\/p\u003e\n\u003ch3\u003e🕰️ The Evidence\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eReference:\u003c\/strong\u003e ZO3552\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel \/ Collection:\u003c\/strong\u003e Super Sea Wolf Pro-Diver\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYear:\u003c\/strong\u003e Unknown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase:\u003c\/strong\u003e Stainless steel, screw-lock crown bearing the Zodiac logo, solid caseback\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCase Diameter:\u003c\/strong\u003e 42 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness:\u003c\/strong\u003e Approximately 14.3 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug-to-Lug:\u003c\/strong\u003e Approximately 49.5–50 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLug Width:\u003c\/strong\u003e 20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDial:\u003c\/strong\u003e Black sunray with Super-LumiNova hands and markers, luminous stick indices\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal:\u003c\/strong\u003e Sapphire, anti-reflective coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBezel:\u003c\/strong\u003e Unidirectional, fully graduated ceramic insert with luminescent markers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement:\u003c\/strong\u003e Swiss Sellita SW200-1 automatic, 26 jewels, hand-winding and hacking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMovement Type:\u003c\/strong\u003e Automatic, normal winding\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e COSC chronometer and ISO certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Reserve:\u003c\/strong\u003e Approximately 38 hours (Sellita SW200-1 specification)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunctions:\u003c\/strong\u003e Hours, minutes, seconds; unidirectional timing bezel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Resistance:\u003c\/strong\u003e 300 metres \/ 30 ATM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet:\u003c\/strong\u003e Stainless steel Jubilee-style brushed seven-link bracelet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClasp:\u003c\/strong\u003e Butterfly deployant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet Fit:\u003c\/strong\u003e Approximately 8-inch wrist\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e Like New — unworn, factory protective stickers in place\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e Box, Papers, and Cards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e🌟 Collector Provenance\u003c\/h3\u003e\n\u003cp\u003eThe Super Sea Wolf line is Zodiac's anchor. The original Sea Wolf arrived in 1953, placing Zodiac among the small group of Swiss houses that built a genuine purpose-made dive watch at the very beginning of the category rather than in response to it. Everything the modern brand does in this space traces back to that watch, and the Pro-Diver is the branch of the family that pushes hardest toward specification rather than nostalgia.\u003c\/p\u003e\n\u003cp\u003eWhere the Super Sea Wolf 53 and the Compression models lean on mid-century silhouettes, the Pro-Diver reads as a contemporary professional instrument: crown guards, a thick bezel with full minute graduation, and a case that wears with deliberate presence. Zodiac markets it explicitly on its ISO rating and 300 metres of water resistance — professionally rated rather than merely dive-styled.\u003c\/p\u003e\n\u003cp\u003eThe certification combination is what collectors tend to latch onto here. A COSC-certified Sellita in an ISO-rated case is a specification sheet usually associated with watches from considerably louder brands, and it is a large part of why the Pro-Diver has a quietly loyal following among buyers who shop on substance.\u003c\/p\u003e\n\u003cp\u003eThere is also the matter of how Zodiac builds. Each Zodiac watch is hand-assembled in Biel-Bienne, Switzerland, and the brand produces its styles in small batches, with references going out of circulation once a batch sells through. The practical effect is that specific Pro-Diver configurations tend to appear and disappear from dealer shelves rather than remaining perpetually available.\u003c\/p\u003e\n\u003ch3\u003e🌟 Technical Provenance\u003c\/h3\u003e\n\u003cp\u003eThe Sellita SW200-1 is the workhorse argument for this watch. It hacks and hand-winds, runs 26 jewels, and is one of the most widely serviced Swiss automatic calibres in circulation — meaning any competent independent watchmaker can work on it without sourcing exotic parts. Chronometer certification adds an externally tested accuracy standard on top of that familiarity.\u003c\/p\u003e\n\u003cp\u003eThe case architecture supports the rating rather than just implying it. A solid caseback and a screw-lock crown carrying the Zodiac logo are paired with crown protection and a sapphire crystal. The ceramic bezel insert is the practical upgrade over aluminium: it resists the scuffing and fading that eventually dulls older dive bezels, and its luminescent markers keep the elapsed-time scale usable in low light.\u003c\/p\u003e\n\u003ch3\u003e🧾 From the Case File\u003c\/h3\u003e\n\u003cp\u003eAt 42 mm across with roughly 14.3 mm of height and a 50 mm lug span, this is a diver with real wrist presence, best suited to medium and larger wrists — and as sized, it is set up for an approximately 8-inch wrist. The brushed seven-link bracelet does useful work here: a Jubilee-style link pattern drapes and articulates more fluidly than a three-link Oyster-type bracelet, which helps a 42 mm case settle rather than perch.\u003c\/p\u003e\n\u003cp\u003eThe 20 mm lug width is the other quiet advantage. It opens the watch to essentially the entire aftermarket strap world — rubber for the water, NATO for the weekend, leather if the mood turns — without hunting down an unusual size.\u003c\/p\u003e\n\u003cp\u003eThen there is the obvious practical case: an unworn watch, stickers intact, with box, papers and cards, purchased pre-owned. The buyer gets a genuinely untouched example and full documentation without paying retail, and with none of the ambiguity that usually accompanies secondary-market condition grading. Note that Zodiac supplies a two-year manufacturer's warranty on new purchases through authorised dealers; any remaining coverage on this example would depend on the original activation date and Zodiac's warranty terms, which BST cannot confirm.\u003c\/p\u003e\n\u003ch3\u003e🗝️ BST Verdict\u003c\/h3\u003e\n\u003cp\u003eA serious dive watch from the house that helped invent the category, specified with a COSC-certified Swiss automatic and an ISO-rated 300-metre case — specification territory that usually costs considerably more attention and considerably more money.\u003c\/p\u003e\n\u003cp\u003eUnworn, stickers in place, complete with Box, Papers, and Cards.
