Coros released the Pace 4 Pro on Tuesday 22 September, the date it had confirmed earlier in the month. It costs £389 in the UK, $449 in the US, €449 in Europe and AU$779 in Australia. It comes in black and white, with silicone or nylon straps depending on the colour. The standard Pace 4 launched at £229, so the Pro is a big step up in price for a range that Coros has always sold on value.
The main changes are to the hardware. Titanium replaces the polymer bezel and sapphire replaces mineral glass. The screen is a 1.47-inch AMOLED rated at 3,500 nits, which Coros says is its largest and brightest yet and 22% larger than the Pace 4's. Coros has also doubled the RAM, which it says makes maps faster to draw and pan than on any previous Coros watch. The watch uses a new multi-channel optical heart-rate sensor. Coros says all of this adds only 11 grams over the previous model.
Battery life improves by nearly 50%. Coros claims up to 60 hours of continuous GPS, or 46 hours with the always-on display switched on, and up to 21 days of everyday smartwatch use, or seven days with always-on. Dual-frequency GNSS, offline maps, storage and sport profiles are carried over from the rest of the range. The Pace 4 already got full mapping in a software update earlier this month.
Some things haven't changed. Like the rest of the Pace line, the Pro has no NFC contactless payments and no music streaming, and it only connects to sensors over Bluetooth, not ANT+. That matters more at £389 than it did at £229. At this price the Pro competes more directly with Garmin, where buyers also get payments, an app store and deeper training features. The specialist site the5krunner says Coros has changed the maths by pricing this close to Garmin.
The Pace line now has three watches with maps and AMOLED screens, and they overlap. The Pro sits above the Pace 4 and takes the spot previously held by the Pace Pro, so choosing between them comes down to how much the titanium case, bigger and brighter screen and longer battery are worth to you. For runners who train on dark winter mornings or race ultras, the screen and battery are real improvements. Runners who mainly want a light, accurate GPS watch will probably find the cheaper Pace 4 still makes more sense.
