A Complete Guide to the Tissot PRX Chronograph

The Tissot PRX Chronograph is the watch everyone was waiting for. It’s the evolution of the wildly popular PRX line, taking that killer 1970s integrated bracelet design and packing it with the mechanical muscle of a Swiss automatic chronograph. What you get is a watch that punches way, way above its weight class in terms of value, making it a serious contender for both newcomers and veteran watch geeks.

A Modern Classic Was Born

When Tissot brought back the PRX, they struck gold. The market was hungry for integrated bracelet sports watches, a look that has come to define a lot of popular modern watches. The first quartz and automatic models were an instant hit due to sharp looks, great wrist feel, and accessible pricing.

But almost immediately, the community wanted "what's next?" The answer, which arrived in 2022, was the Tissot PRX Chronograph. This was no ordinary update—it introduced a full automatic chronograph movement, a rare sight at this price. The move confirmed Tissot’s ambition and made the PRX a talking point among enthusiasts and collectors.

So, What's the Big Deal?

The PRX Chronograph stands out because it offers a high-end Swiss experience without the premium price tag.

• That iconic '70s-inspired tonneau case and integrated bracelet

• Genuine Swiss automatic chronograph movement with display sapphire caseback

• Finishing on par with much pricier watches

Inside is the Valjoux A05 H31 calibre, with a robust 60-hour power reserve and housed in a 42mm stainless steel case. The exhibition caseback is a welcome touch for the price segment, allowing a view of the intricate mechanics.

Exploring the Design and Specifications

Design is where the PRX Chronograph shines. Inspired by integrated bracelet sports watches of the 1970s, it feels both classic and modern. Core specs:

• 42mm case diameter

• 14.5mm case thickness

• 316L stainless steel tonneau-shaped case

• Sapphire crystal with anti-reflective coating

• Water resistance 100 meters

• Sapphire caseback

Though the case sounds large, smart design decisions (like a relatively short lug-to-lug of around 46.5mm) make it comfortable for a broad range of wrists.

A Closer Look at the Dial

The PRX Chronograph comes in “panda” (silver/white dial with black subdials) and “reverse panda” (blue or black dial with contrasting light subdials) variants for excellent readability. Subdials are at 3, 6, and 9 for 30-minute, 12-hour, and running seconds, with a date window at 4:30. Luminous hands and applied baton indices ensure legibility day and night.

The Integrated Bracelet

The single-link, tapered bracelet is one of the PRX’s highlights. Its brushed and polished finishing matches the case, and it’s secured with a butterfly clasp with push-button releases. The seamless integration adds comfort and visual appeal.

Understanding the Valjoux A05 H31 Movement

The Valjoux A05 H31 is a heavily upgraded version of the ETA/Valjoux 7753. Its most important features include:

• 60-hour power reserve

• 28,800 vibrations per hour (4Hz)

• 30-minute, 12-hour, and running seconds subdials

• Date adjustment is done via a recessed button at 10 o’clock on the case (not by crown quick-set)

A View Through the Caseback

The exhibition caseback reveals the decorated movement, including a custom Tissot rotor, visible balance wheel, levers and gears of the chronograph mechanism, and perlage finishing on bridges. It’s a visually satisfying aspect for mechanical watch enthusiasts.

How It Wears in the Real World

• 42mm case diameter

• 14.5mm thickness

• About 46.5mm effective lug-to-lug

• 100 meters water resistance

Thanks to the integrated design and short effective lug-to-lug, the PRX Chronograph sits comfortably on most wrists. The tapered bracelet adds to everyday comfort, while Super-LumiNova on hands and indices aids nighttime use.

Comfort and Balance in Daily Use

A sharply-tapered bracelet, snug fit, and secure butterfly clasp all combine for excellent daily wear. The watch avoids the top-heavy feel common among large chronographs.

The Tactile Experience

The chronograph pushers are tactile and satisfying. If you like to personalize, Tissot and several third-party brands now offer straps that fit the PRX’s specific case shape, though you must ensure end-link compatibility.
