Creator Consensus

Creator Consensus

Very positive

5 reviews: 5 positive, 0 mixed, 0 negative. 5 of 5 recommend it.

Every reviewer recommends it, and most praise it as a period-correct revival of the 1967 original. The bracelet is liked across the board, with most singling out the toolless micro-adjust clasp. Most also find the slim case wears comfortably and discreetly, and appreciate the neatly framed trapezoidal date window.

Where they differ. While most like the slim profile, a couple of reviewers find the straight lugs sit high on the wrist. Some also miss lume for low-light reading and find the push-pin links tedious to size.

Video, 8 minHands-on reviewDec 2025

Very positiveRecommends

Praises the Ultra-Chron Classic as a remarkably faithful revival of the ref. 8309, with slim cases, two well-judged sizes and an excellent micro-adjust bracelet. Minor reservations cover the plain, unlumed dial, high-sitting lugs and pin-and-collar links.

Suits: Those wanting a vintage-looking, vintage-wearing dress-leaning watch over a sportier diver

The reviewer fell in love with the Ultra-Chron Classic, praising its clean vintage design, thinness, tapering bracelet, micro-adjust clasp and finishing at a good price. The only complaints are the lack of lume and the modest 50m water resistance. For a 7.5in wrist, the 37mm seems better.

New Longines Ultra Chron Classic, Perfection

Very positiveRecommends

The reviewer is enthusiastic about the 40mm Ultra-Chron Classic, praising its faithful vintage styling, detailed sunburst dial and exceptionally smooth, accurate 10-beat movement. Minor quibbles are the small crown, push-pin bracelet and long straight lugs. The reviewer argues it beats buying a vintage original.

Longines’ Ultra-Chron Classic is a Double-Certified, High-Beat Chronometer

ArticleReactionOct 2025David Ichim

PositiveRecommends, with caveats

The reviewer sees the Ultra-Chron Classic as modern Longines at its best, with solid build, a high-spec double-certified 5Hz movement and sensible pricing. The faithful vintage design is seen as plain and unexciting, and may struggle to stand out.

Not a review of the watch in hand (news, a guide or a reaction), so it isn't counted.

What the review says, point by point
Designmixed
  • Finds the faithful styling unexciting, retaining an all-business look of the era.
  • Suspects the pared-back look will struggle to stand out in the current market.
Dialpositive
  • Considers the central crosshairs a thoughtful precision-timekeeper detail.
  • Feels the applied Ultra-Chron logo helps set the watch apart within the Longines range.
Case & proportionspositive
  • Counts proper sizing among the watch's strengths.
  • Finds the just-under-11mm robust proportions appropriate, especially for the 37mm version.
  • Suggests smaller sizes suit this style of watch well, implicitly favouring the 37mm.
Bracelet & strapmixed
  • Considers the grooved five-link bracelet somewhat generic in design.
  • Values the micro-adjust clasp as something buyers want in this type of watch.
Movementpositive
  • Highlights the 5Hz, double-certified movement as notably high-spec.
  • Views the 52-hour reserve as an achievement given the 5Hz upgrade to an existing base.
  • Praises Longines for going beyond COSC with TIMELAB testing, though perhaps less exacting than METAS.
Finishing & buildpositive
  • Credits the watch with a solid build typical of modern Longines at its best.
Originalitypositive
  • Praises Longines for reviving archive designs built to modern standards.
  • Finds the reissue impressively faithful to the original's style.
Valuepositive
  • Describes the pricing as sensible.
  • Considers the bracelet surcharge modest.
  • Notes it is expensive for Longines but competitive as a high-frequency chronometer.
Compared with
  • Jaeger-LeCoultre Geophysic E168: Shares the same criticism of an unexciting, all-business period design.
  • IWC Ingenieur ref. 666: Shares the same criticism of an unexciting, all-business period design.
