Few watches have reshaped the affordable mechanical landscape quite like the Tissot PRX Powermatic 80. What started as a quartz revival of a 1978 design quickly became one of the most talked-about integrated-bracelet watches at its price point, and the automatic version is the model that turned the PRX from a fun retro piece into a genuine modern icon.
The Automatic Tissot PRX
The headline feature is the Powermatic 80 movement, an automatic calibre based on the ETA C07 architecture and tuned to deliver roughly 80 hours of power reserve. In plain terms, you can take the watch off on Friday evening and it will still be ticking when you pick it up on Monday morning. That kind of reserve was almost unheard of at this price when the watch arrived, and it remains one of the PRX Automatic’s strongest selling points.
Through the sapphire caseback you can watch the rotor spin and the balance oscillate. Many versions ship with the Nivachron hairspring, which improves resistance to magnetism and everyday knocks, making the watch a sensible daily companion rather than a delicate showpiece.
Design and dimensions
The case measures 40 mm across with a slim integrated steel bracelet that tapers elegantly into the case. The crystal is sapphire, water resistance is rated to 100 metres, and the whole package wears far more expensively than its price suggests. The famous “tapisserie” waffle dial, available in a long list of colours from classic blue and silver to ice blue, green, and black, catches the light in a way that draws comparisons to luxury sports watches costing many times more.
In short, the design that started life in 1978 has aged into one of the most recognisable looks in the affordable watch world, and Tissot has been smart about expanding the range without diluting it.
How the range has grown
When we first wrote about the PRX Automatic it was almost impossible to find in stock. That is no longer the case. Tissot has built the PRX into a full family that now includes:
- The 40 mm Powermatic 80 on a steel bracelet in a wide spread of dial colours.
- A 35 mm Powermatic 80 for those who prefer a smaller, more vintage-correct wrist presence.
- Dressier variants with sunburst dials, plus two-tone and gold PVD options.
- The PRX Chronograph, which adds a Valjoux-based automatic chronograph movement for buyers who want more complication.
- Higher-end “Digital” reissues and limited editions that lean into the watch’s late-1970s heritage.
Quick-release spring bars on most references also make it easy to swap the steel bracelet for leather or rubber, so a single watch can move from the office to the weekend without tools. If you want to change the look, we have also put together a guide to the best Tissot PRX straps and alternatives.
Is it worth it?
For anyone looking for a first proper mechanical watch, or a knockabout integrated-bracelet piece that does not need babysitting, the PRX Automatic is one of the easiest recommendations in the category. You get an 80-hour movement, a sapphire crystal, genuine Swiss manufacturing, and a design with real pedigree, all for a fraction of what the obvious luxury alternatives command. The quartz version remains a great option if you want the look at a lower price and do not mind a battery, but the automatic is the one that earns the PRX its reputation.
What movement does the Tissot PRX Automatic use?
It uses the Powermatic 80, an automatic Swiss movement based on the ETA C07 with around 80 hours of power reserve. Many versions include a Nivachron antimagnetic hairspring.
What size is the Tissot PRX Automatic?
The standard model is 40 mm, and Tissot also offers a 35 mm version. Both have sapphire crystals and 100 metres of water resistance.
Is the PRX Automatic better than the quartz version?
It depends on what you want. The automatic offers a mechanical movement and an exhibition caseback, while the quartz is cheaper, thinner, and lower maintenance. Both share the same iconic design.
