Don't miss the next drop
Anthracite sunburst, applied steel batons, “T SWISS MADE T” along the lower edge, and the Longines winged hourglass sitting just under twelve. To us, the Admiral HF in steel is one of the quietly underrated Longines references of the early-1970s, in our opinion the closest the brand came to a properly serious dress-sport piece in the years before quartz redrew the catalogue. Everything about this Ref. 2301-1 reads as the moment Longines stopped apologising for the round dress watch and started building a tonneau case that could carry a high-beat movement without flinching.
Longines was founded in Saint-Imier in 1832, and across the postwar decades the manufacture pushed the chronometry side of the business harder than almost any other Swiss house, posting observatory results that put the brand among the genuine technical leaders of the era. The Admiral line had launched in 1957 as the American-market companion to the Conquest, and by the late-1960s the catalogue had bifurcated into the date-and-day Admiral 5-Star automatics and the leaner, more chronometrically ambitious Admiral HF references. HF meant high frequency. Longines had committed to the 36,000 semi-oscillation movement architecture as a route to better timekeeping inside the same manual-wind footprint, and the 2301-1 was the steel cushion-cased dress version of that idea.
The caliber is the Longines 6942, the manual-wind high-beat from the 690-series family that Longines developed specifically to compete in the high-frequency arms race against Zenith’s El Primero and Girard-Perregaux’s 36,000 bph chronometer movements. Seventeen jewels, 28mm in diameter, 3.85mm thick, running at 28,800 beats per hour, with Kif-Ultraflex shock protection and a micrometer regulator. The headline feature is the zero-reset hacking seconds, the kind of complication that quietly tells you a movement was engineered for collectors who care: pull the crown and the seconds hand sprints forward to twelve and stops there, ready to be synchronised against a time signal the moment you push the crown home. The 6942 is the Longines Admiral HF caliber that period collectors actually chase, and our movement-side photograph reads “LONGINES” arched across the upper bridge, the caliber number “6942” stamped in the cartouche, “WATCH Co SWISS” alongside, “SEVENTEEN 17 JEWELS” beneath, and “UNADJUSTED” running below.
The case is the tonneau steel Admiral HF profile, 34mm across the bezel with a 40mm lug-to-lug span, 18mm between the lugs, and the sharply chamfered downward-sloping lug-cuts that give the reference its instantly recognisable silhouette. Mirror-polished tops, satin-finished case sides, and a thin smooth bezel that lets the dial do the talking. Honest wear scatters across the case sides and the lug facets exactly as a steel watch worn for fifty years should look, with the polished surfaces still reading sharply and no signs of heavy refinishing. The screw-down caseback carries the period Longines stamping verbatim: “LONGINES” across the upper face, the winged hourglass logo beneath the wordmark, “FAB SUISSE” and “SWISS MADE” stacked through the centre, and “ACIER INOX 2301-1” running across the lower face to identify the steel construction and the full reference. The crown is the signed Longines component with the brand wordmark engraved around the toothed outer edge and operates with the positive click a properly serviced 6942 should give.
The dial is the headline. An anthracite grey sunburst finish radiates from the centre in concentric rays that pull noticeably blue when the light tilts off-axis and read as a deep gunmetal grey straight on, the kind of factory finish that photographs differently in every frame. Applied polished steel baton markers sit at every hour with a slightly wider tapered marker anchoring twelve, the printed Longines wordmark and winged hourglass logo sit just below twelve, and “ADMIRAL HF” is printed in two clean lines above six o’clock. There is no date and no sub-seconds register, just a centre-sweep seconds tracking across the minute marks. Slim luminous fill runs through the broadarrow hour and baton minute hands, both aged to a warm cream that matches small lume dots set beneath the applied batons, and the printed “T SWISS MADE T” along the lower dial edge confirms the tritium-era production exactly where it should be on a 1972 example. The dial is unrestored and reads as factory original through every photograph, with the sunburst pattern still active under raking light.
We have paired the watch with one of our anthracite Italian suede straps in dark grey, the texture and tone reading as a natural counterpart to the sunburst dial and the brushed steel case sides, finished with an OTTUHR signed buckle. The strap pulls the dial colour out to the cuff without competing with it.
Serviced in-house at OTTUHR and backed by our 2-year mechanical warranty, this is the Longines Admiral HF we genuinely enjoy bringing in. Factory original anthracite sunburst dial, matched factory hands and markers, signed crown, “ACIER INOX 2301-1” caseback intact, and the high-beat caliber 6942 with its zero-reset hacking seconds running cleanly. For the collector who values high-beat manual-wind chronometry over date-window automatics, who reads sunburst dials as canvas rather than catalogue, and who wants a Longines that does the technical work without dressing up as a sports watch, this Admiral HF reads as one of the more honest steel dress references of the period to us.
