Two-tone sector dials are a 1940s genre we never tire of, and to us, the Movado Acvatic Ref. 11730 is one of the more quietly compelling expressions of the form. The architecture is straightforward: a darker honey-gold center field, a creamier outer chapter ring carrying full Arabic numerals, a thin printed ring dividing the two. What sells it is how those two zones have aged differently. The center has gone deep and speckled, almost mottled, while the chapter ring has stayed lighter and warmer, creating a two-tone effect that wasn’t planned by anyone in La Chaux-de-Fonds in the 1940s and is now the entire reason to spend ten minutes looking at this watch.
There was a stretch of the twentieth century, before the Museum dial collapsed Movado’s identity into a single design idea, when the brand sat comfortably alongside Omega and Longines in the upper-middle tier of Swiss watchmaking. Founded by Achille Ditesheim in 1881 in La Chaux-de-Fonds, Movado built a reputation through the 1920s, 1930s and 1940s for accurate movements and editorially confident dial design. The Acvatic line, introduced in 1935, was Movado’s entry into the waterproof category that Rolex had publicly claimed with the Oyster. The pseudo-Latin spelling, somewhere between aqua and aquatic, was Movado’s own branding choice, and it appears in period advertising exactly the way it appears on this dial.
The movement inside is the Movado caliber 150MN, a 15-jewel manual-wind ébauche of 10.25 lignes (roughly 23mm) running at 18,000 vibrations per hour with a Breguet overcoil hairspring and a power reserve in the 44-hour range. The 150 family was in production at Movado from 1926 through 1954, which means the 150MN sits across the back half of Movado’s manufacture-movement era. The MN suffix is the part Movado wanted you to read off the dial. It designates the non-magnetic configuration, signalled in plain text on the lower half of the dial, and it was the version specified for environments where stray magnetism could pull a watch off rate. The 150MN runs an indirect center seconds train rather than a subseconds layout, which is the thin black sweep hand you see ticking from the center of the dial.
The case is what makes the Acvatic conversation interesting. Movado contracted François Borgel, by then operating as Taubert et Fils in Geneva, to build a true waterproof case for the line, the same Borgel workshop that had filed the first water- and dust-proof pocket watch patent in 1891 and that supplied cases for some of the earliest reference Patek Philippes. The exterior caseback on this Ref. 11730 carries the familiar rectangular FB PATENT cartouche with the Geneva cross hallmark on one flank and STAINLESS stamped on the other. Below those, you can read the engraved case number 0155228, the reference 11730, and a small grid of watchmaker service marks, the clearest of which reads JN 2-15-53, dating one of its mid-century servicings to February 1953. The case itself wears 28mm across with a 39.5mm lug-to-lug and 16mm lug width, and the architecturally faceted bracket-style lugs are the visual signature, sharply cut, brushed on top, polished on the sides, with the kind of mid-century industrial confidence you do not get on a softer round case. The smooth screw-down caseback shows decades of honest wear, scratched the way a watch that lived on a wrist should be, with the case lines themselves still crisp.
Back to the dial, because it really is the headline. The MOVADO signature sits cleanly printed under 12 in black, with the NON-MAGNETIC callout running in smaller black text above the 6 position. The Arabic numerals are full and complete, in a serif-leaning Art Deco style typical of the line and the era, painted onto the chapter ring rather than applied. The outer minute track is railroad-style with 25, 30 and the rest of the five-second numerals running around the periphery. The hour and minute hands are slim lance batons with their original luminous fills aged to a creamy oxidized tan that matches the dial chapter ring almost exactly, and the indirect center seconds is a long thin black hand sweeping from the central pinion. We see no evidence of redial work. The printing is sharp, the speckling on the center field is organic and asymmetric in the way real aging is, and the hand patina matches the dial patina, which is the first sanity check on any 1940s Movado dial claim.
We have paired it on a cognac grained leather strap with cream contrast stitching, which picks up the chapter ring tone almost exactly and lets the dial center hold the visual weight. On the 16mm lug width the strap sits cleanly, and on a small-to-medium wrist the 28mm by 39.5mm proportions read as quietly correct for a 1940s sport piece rather than undersized in the modern sense.
Serviced in-house at OTTUHR and backed by our 2-year mechanical warranty, this is a piece we genuinely enjoy having in the case. The François Borgel provenance, the documented mid-century service history engraved on the back, the in-house Movado caliber, and a dial that has aged into something the original designers could not have planned. Those things stacked together are what a thoughtful vintage Movado purchase looks like to us. For the collector who has worked past the obvious 1960s and 1970s sport references and is now hunting earlier, quieter, more architectural Swiss watchmaking, the Acvatic Ref. 11730 is exactly the kind of mid-century piece we love bringing back into circulation. In our opinion, it is one of the more rewarding two-tone sector dials of its decade.
