Modelled on the Chrono-Matic GMT Count-Down from the 1970s, the Chrono-Matic 50 in blue stays true to its predecessor in style. The limited edition retains the five-crown configuration and retains the bold, helmet-shaped 48 mm case, though it forgoes the GMT function. As is typical for Hamilton, the new Chrono-Matic 50 is powered by a high-spec ETA movement and priced affordably.

Initial thoughts

For several years now, vintage reissues been a dependable strategy for watch brands. Rather than venturing into entirely new designs with unpredictable results, companies are playing safe by relying on the established appeal of reissues. But there are a lot of reissues already on the market, with more being launched seemingly all the time.

The Chrono-Matic 50 in blue exemplifies this. Having introduced a black version in 2019, Hamilton has done the same in blue. The new Chrono-Matic 50 stands out from the average reissue in two respects. One is the better-than-average movement for the price range thanks to Hamilton being a sister company of ETA, the biggest maker of mechanical movements in Switzerland. The second is the historical basis of the watch; Hamilton did actually make something like that in the past, which gives this a legitimacy that startups lack.

The case is somewhat oversized for my personal preference, though it is sized similarly to the chunky vintage original.It does have a unique design and layout, and with a retail of US$2,545, the Chrono-Matic 50 is also well priced.

Staying true to the original

The standout feature is the helmet-shaped case, measuring large 48 mm by 52 mm in diameter and 16.05 mm thick that is similar to the dimensions of the original.

Water-resistant to 100 m, the case boasts a radial brushed finish on the front, along with an unusual layout of two crowns and three pushers. The orange pushers operate the chronograph, while the black pusher at 10 o’clock serves as a date corrector, and the second crown at eight rotates the inner countdown bezel.

The Chrono-Matic 50 features a “reverse panda” dial with white sub-dials — one displaying small seconds at nine o’clock and another for elapsed minutes at three o’clock. Subtle orange accents enhance its appeal and add to the 1970s look.

The watch is driven by the self-winding H-31, an upgraded version of the Valjoux 7750. The H-31 is an industrial workhorse with a 60-hour power reserve and upgrades including a reworked oscillator.
