PRX Quartz Chronograph the 1978 shape gets a £430 stopwatch

What is new about the PRX Quartz Chronograph?

Since the PRX returned in 2021, Tissot has offered it as a quartz three-hander, as a Powermatic 80 automatic and as a large automatic chronograph. What it has not offered is a quartz chronograph, even though the original 1978 PRX was itself a quartz watch. The PRX Quartz Chronograph, announced in September 2026, fills that gap. Time+Tide dated the launch to 15 September, and Tissot's UK site lists it at an RRP of £430.

That price matters. Oracle of Time puts the automatic PRX Chronograph at £1,695, so the quartz model costs roughly a quarter as much while keeping the integrated bracelet, the barrel-shaped case and the vertically brushed dial. There are three references: silver (T137.417.11.031.00), black (T137.417.11.051.00) and the blue covered here, T137.417.11.041.00.

How big is it, and how will it wear?

Tissot quotes a 41 mm case, 41 mm long and 11.65 mm thick, with a weight of 151 g on the bracelet. That makes it a millimetre larger than the 40 mm three-hand PRX but noticeably slimmer than the automatic chronograph, which runs well past 14 mm.

The PRX case has almost no lugs. The bracelet flows straight out of the case, so the watch wears longer and flatter than the diameter suggests. As a rough guide:

• Under 16 cm: the case will look broad, and the top link will overhang the wrist edges.
• 16 to 18 cm: the sweet spot, with the integrated bracelet curving down cleanly.
• Over 18 cm: it will look neat rather than large.

The quick-release bracelet uses a butterfly clasp with push-buttons. Tissot lists the bracelet separately as T605052213, which is handy if you want a spare or a different finish later.

What movement does it use, and how accurate is it?

Inside is the ETA G10.212 PowerDrive quartz chronograph. Tissot lists a 30-minute counter, a 1/10-second counter, a central 60-second chronograph hand, add and split functions, a date at 4 o'clock and an end-of-life indicator that warns when the battery is fading. European retailer Helveti quotes accuracy of plus or minus 15 seconds a month.

The 1/10-second counter is the clever part. Once the stopwatch is stopped, it shows tenths of a second, a reading the mechanical PRX Chronograph cannot give. The split function lets you freeze an intermediate time while the stopwatch keeps running, which is useful for laps.

How well is it built?

The specification is generous for £430:

• Crystal: sapphire.
• Water resistance: 10 bar (100 m), with a screwed caseback.
• Case and bracelet: 316L stainless steel, mixing brushed and polished surfaces.
• Lume: Super-LumiNova on the hands and indices.

The blue dial has the PRX's fine vertical brushing, three blue sub-dials and a white date window. Gear Patrol notes the pushers are shaped to follow the line of the case rather than sticking out as round buttons.

Is it good value against its rivals?

The closest like-for-like rival is Citizen's Racing Chronograph CA4714-55A, a 39 mm solar chronograph that Citizen UK lists at £369. It never needs a battery change and is smaller, but it has a mineral crystal rather than sapphire and a more vintage look.

Within Tissot's own range, the choice is between this and the £1,695 automatic PRX Chronograph. The automatic has a sweeping seconds hand and a mechanical movement to look at through the caseback. The quartz version is thinner, more accurate and far cheaper. For most people who simply like the PRX design, the quartz model is the more sensible buy.

What is the catch?

Three things. First, this is quartz: the running seconds hand ticks once a second, and there is no display caseback. Second, the integrated case limits strap choice to Tissot's own quick-release options. Third, the dial is busy. With three sub-dials, a date and the PRX name, it is less clean than the three-hand PRX.

The watch is also too new for meaningful owner feedback. Early coverage focuses on the price and the slimmer case, but there is not yet any long-term owner discussion of the bracelet or movement.

“A quarter of the price of the automatic, and the only PRX chronograph that reads tenths of a second.”
