Don't miss the next drop
There is a category of vintage watches we keep coming back to where the dial has spent fifty-something years quietly rearranging itself, and the result is a piece nobody else owns the duplicate of. The Wittnauer Automatic Day/Date Ref. 3503 in front of us is one of those watches. The blue dial that left Switzerland in the early 1970s as a pristine lacquered surface has, in the decades since, fractured into a wide network of fine spider-web cracks across the entire face, and in our opinion that transformation makes this specific 3503 more interesting than the day-it-shipped version ever was.
Wittnauer by the early 1970s was operating as the American-market arm of the Longines-Wittnauer Watch Company, with full access to Swiss-grade movements and the Longines distribution network behind it, but with the editorial license to chase the bolder, more expressive case shapes that the American buyer of the period was actually walking into department stores asking for. The Ref. 3503 lands squarely in that brief: a Swiss automatic day-date dressed inside a cushion case profile the parent brand would not have signed off on, sold at a price point that put a proper self-winding caliber on the wrists of buyers who in another decade would have bought a quartz instead.
Inside is the Wittnauer caliber D11KAS-1, signed in gold lettering across the automatic rotor as WITTNAUER WATCH CO INC. The D11KAS is the Wittnauer-branded version of the Record caliber 1958, the base ebauche that Record Watch Co supplied to both Wittnauer and Longines in this period, which pulls it directly into the Longines 503 family that powered the parent brand’s calendar automatics. The configuration is 17 jewels running at 19,800 vibrations per hour with a 44-hour power reserve, automatic winding with a sweep seconds hand, and the stacked day-and-date complication that was the headline upgrade Wittnauer introduced on the D11KAS family in roughly 1968. The Record-supplied base is genuinely strong: a clean, easily serviced movement watchmakers still recognize on sight and stock parts for, which is not something you can say for every American-branded Swiss caliber of the era.
The case is stainless steel in a cushion profile at 35.7mm across, 40mm lug-to-lug, with the 19mm lug spacing integrated into the bracelet so the geometry reads as one continuous unit from clasp to crown. The sides of the case are sharply faceted, with brushed flanks and a polished bevel pulling daylight across the angles in a way that gives the watch real architectural weight on the wrist for a sub-36mm dress automatic. The exterior of the caseback is the plain steel back you would expect from this period, with concentric circular tool marks in the center and an honest scratch field across the perimeter from decades of being unstrapped and set face-up on dresser tops. The inside of the caseback is stamped clearly: WITTNAUER WATCH Co. INC. SWISS arcs around the perimeter and the caliber plus reference stamp at center reads D11KAS-1 over 3503, with a small W maker’s mark beside it. The crown sits at three o’clock with vertical fluting and threads cleanly.
The dial is the headline. The lacquered surface started life as a deep blue fume, brighter toward the center and darkening to near-black at the perimeter, with the Wittnauer house signature applied in silver below twelve as the stylized W emblem over WITTNAUER over Automatic in cursive. The dial reads with painted silver Arabic numerals at every hour position in a slightly playful italic serif, an inner chapter ring carrying the printed minute track, and a vertically stacked day-date window at six o’clock framed in polished steel, with the day printed in white on a blue ground and the date printed in white on a red disc, which is the tricolor calendar detail defining this configuration. T SWISS T sits clean at the very bottom of the dial outside the six o’clock marker. The story, though, is what the lacquer has done with itself in the years since: a fine spider-web craquelure pattern runs across the entire dial face, a network of hairline cracks fanning out from the center and across the colored zones, which is the namesake this Ref. 3503 has earned among collectors. The lance-shaped hour and minute hands are stainless with the original cream-toned aging visible across the hand surfaces, and the slim sweep seconds hand is intact. Everything on the dial is factory-original, and the patina is the point.
The bracelet is the original stainless steel brick-link with a polished fold-over clasp, color and material both factory, and it ties the cushion case profile into a single integrated visual the way the Ref. 3503 was sold from the dealer in the first place. The links and clasp wear honestly with the case, which is what you want from a complete period-correct package rather than a watch that has been quietly refreshed somewhere along the way.
Serviced in-house at OTTUHR and backed by our 2-year mechanical warranty, this Ref. 3503 is one of those vintage Wittnauer Automatic Day/Date pieces where the dial is doing work the marketing brief never anticipated. For the collector who values one-of-one organic patina and a Record-derived Swiss day-date caliber over a glossy-from-the-vault redial that would have erased all of it, this 3503 is, to us, exactly the kind of watch worth buying because it cannot be repeated.
