Introducing Hamilton Chrono-Matic 50 Auto Chrono in Blue

In 2019, Hamilton unveiled the Chrono-Matic 50, a modern reimagining of the brand's vintage Count-Down GMT Chrono-Matic from the early 1970s. Featuring a robust, rounded case with two crowns and three pushers, the Hamilton Chrono-Matic 50 draws clear visual inspiration from its 1970s predecessor. This timepiece celebrates Hamilton's contribution to the development of one of the world’s first automatic chronograph movements, created in collaboration with Heuer, Breitling, and Dubois Dépraz.

For 2025, Hamilton has released a new version of the Chrono-Matic 50, featuring a bold blue and orange racing-themed color scheme. The new Hamilton American Classic Chrono-Matic 50 Auto Chrono Limited Edition continues the legacy of this iconic timepiece.

Crafted from stainless steel with a brushed finish, the Hamilton Chrono-Matic 50 Auto Chrono Limited Edition boasts a large case measuring 48.5mm in diameter and 16.05mm in thickness. The top of the case is protected by a box-shaped sapphire crystal, while the caseback is engraved with the limited-edition number, one of only 150 pieces. With a water resistance of 100 meters, the watch is as durable as it is stylish. 

The right side of the case features the crown and orange pushers, while the black pusher at 10 o’clock serves as a quick date corrector. The second crown at 8 o’clock operates the countdown bezel.

The dial of the Hamilton Chrono-Matic 50 Auto Chrono Limited Edition features a striking dark blue surface, accented with white subdials and orange details. A speedometer-inspired register at 9 o’clock displays the running seconds, while a 30-minute counter is positioned at 3 o’clock. At 6 o’clock, a circular date window reveals a white calendar disc. 

The dial is illuminated by luminous hands and applied hour indices. Surrounding the dial are two distinct scales: a tachymeter scale, and between the tachymeter and the central dial section, a rotating internal bezel with an orange 60-minute countdown scale. The split-color finish, combining white and blue, allows the Chrono-Matic 50 to count up or down, depending on the elapsed time measurement.

Powering the Hamilton Chrono-Matic 50 Auto Chrono Limited Edition is the brand’s Caliber H-31 automatic chronograph movement, a bi-compax version based on the Valjoux 7753 architecture. Despite maintaining the same 28,800vph (4 Hz) operating frequency as the base caliber, Hamilton’s Cal. H-31 is optimized to provide a longer 60-hour power reserve. The movement is equipped with an open-worked rotor featuring Hamilton’s signature H-shaped logo.

The watch is paired with a blue calfskin leather strap that complements the dial's hue. The strap features a perforated design, revealing a vibrant orange internal layer, and is secured with a stainless steel pin buckle.

The Hamilton Chrono-Matic 50 Auto Chrono Limited Edition is a limited release of 150 pieces, priced at CHF 2,495 (approximately AED 9,985).
