Montblanc has dropped its new Summit 3 smartwatch, and it's the first non-Samsung device to run Wear 3.0.

Following on from 2021's cheaper Summit 2 Lite, the Montblanc Summit 3 lineup includes three titanium case options: grey (with black calf and blue rubber straps); black (black calf leather and black rubber straps); and bicolor (black and silver) green leather and black rubber straps.

It really looks the part from the press images released by Montblanc.

Update 24/07: We added in official specs and features from Montblanc

Wear OS 3.0 on board

It features a 42mm case, so it should be manageable to wear, 1.28" AMOLED display with a chunky 416 x 416 resolution.

The big story here is, of course, Wear OS. Montblanc says its Summit 3 is powered by the “latest version of Wear OS by Google."

It as the Qualcomm Snapdragon 4100+ processor, which seems to be the minimum requirement for running Wear OS 3.0, so it’s all good from that respect.

And the official specs state that the watch is compatible with iOS – which would be the only Wear OS 3.0 device to do that.

The Summit 3 would be only the second smartwatch run Wear 3.0, after the Samsung Galaxy Watch 4 launched with the OS back in 2021.

Wear OS 3.0 is scheduled for the Google Pixel Watch (slated for Fall 2022), and it should land on a series of existing smartwatches already running 4100+. That includes the Fossil Gen 6 as well as Skagen Gen 6 smartwatches, TicWatch Pro 3 and Tag Heuer Connected Calibre E4.

However, there's been little word on when those updates will happen, with Fossil recently hinting that it would be delayed until the end of the year.

New Summit 3 video shows off Wear OS 3.0

And Montblanc have also released a new video, showing off the functionality off the watch – and it offers one of the best glimpses we've had so far of Wear 3.0 in its native state.

Remember that the Galaxy Watch 4, the only Wear OS watch to date, uses the One UI skin – which makes it look and feel like a Samsung smartwatch. The Summit 3 should feel far more like a standard Wear OS device.

Fitness, sensors and price

Montblanc says that its improved the fitness tracking experience – and you can now follow workouts from the watch itself. However, it seems that the fitness tracking won't be powered by Fitbit, as we've seen on the Google Pixel Watch.

There's a heart rate sensor, barometer and accelerometer – and there's dedicated GPS for tracking of outdoor workouts. It's water-resistant to 50m thanks to a 5ATM rating.

Tracked metrics include step tracking, sleep monitoring including the different sleep phases, and blood oxygen measurement

In terms of battery life, Montblanc promises improved battery ‘capacity’ over the Summit 2 – without any further details. We think it’s safe to assume that it’s still a single day.

The Montblanc Summit 3 arrives 15 July for €1,250 – you can check out the official page here.
