The Montblanc Summit 2 was the first smartwatch to use Qualcomm’s Snapdragon Wear 3100, but the chip did not make it dramatically faster or turn it into a multi-day everyday smartwatch. Its clearest benefit was power-aware ambient display behavior and a watch-only mode. In Droid Life’s October 2018 review, ordinary use still called for roughly daily charging; the Summit 2’s strongest case was its polished luxury-watch design, not a transformative processor upgrade.
What the Snapdragon Wear 3100 changed
The Summit 2 paired the Snapdragon Wear 3100 with 1 GB of RAM and 8 GB of storage. Droid Life’s October 2018 reviewer found everyday interactions smooth: apps opened, notifications appeared, and the touchscreen responded well. But the review did not find a dramatic speed jump over recent watches using the Wear 2100.
The more visible difference was power-aware behavior. The platform enabled more colorful watch faces in the dimmed ambient state and a dedicated watch-only mode. That made the 3100 a useful refinement to the Wear OS experience, particularly when the display was not fully lit, rather than a generational performance leap.
Battery life: daily smartwatch use versus watch-only mode
The standard Summit 2 has a listed 340 mAh battery. Battery life in the 2018 review varied with settings: with tilt-to-wake off, the reviewer used the watch through a day, including a workout, and reported about 30% remaining the following morning. With tilt-to-wake on, the reviewer often reached about 20% before bed. These are one reviewer’s results, not guaranteed runtimes.

- Watch-only mode: Droid Life described up to a full week in this reduced-function mode. It disables everything except a single watch face, so it is not a week of normal smartwatch use.
MrMobile’s separate review also criticized battery life relative to the promise of the 3100 and called the charging cradle frustrating. That is a reviewer’s assessment, not evidence of current charger availability.
Design and display are the Summit 2’s strongest points
Droid Life reviewed the 42 mm steel version, describing its polished and brushed finish, manageable size, and distinctly watch-like presence. The reported specifications are a circular 1.2-inch AMOLED display with 390 × 390 resolution and 22 mm bands. The reviewer praised its brightness, readability, and touch response; these are contemporary observations, not current comparative tests.

Montblanc’s watch faces were another part of the appeal, complementing the physical case rather than making the 3100 itself a compelling reason to upgrade. The result is a luxury-styled smartwatch whose materials and presentation carry more of its identity than raw speed.
Workouts and Wear OS features
The review considered GPS and heart-rate tracking adequate for casual exercise, and the reported run and workout battery results show that the watch could handle those sessions. That does not make it a dedicated sports watch: Digital Trends likewise framed it as suitable for casual workouts and suggested serious athletes look at a fitness-focused alternative. Exercise tracking is best treated as a useful secondary feature to the design and general smartwatch experience.

Wareable’s review summary describes familiar Wear OS functions including notifications, Assistant support, on-watch app downloads, and customizable faces. These are launch-era descriptions; current service availability, software support, and phone compatibility are not established here.

Droid Life listed the standard Summit 2 at $995 at launch in 2018; that is historical launch pricing, not a current quote. At that price, the review’s findings point to a clear trade-off: the refined case and Montblanc styling offered the premium appeal, while the new chip provided incremental practical gains rather than a substantial speed or ordinary battery-life transformation.

There is no verified current price or like-for-like current competitor testing here, so the launch review cannot establish whether a remaining-stock or used Summit 2 is a good buy today. For a present-day purchase, condition, battery health, software support, and the seller’s price would need to be assessed separately.
Summit 2 and Summit 2+ are different models
The Summit 2+ is a later cellular model announced in 2020, not another name for the standard 2018 Summit 2. Qualcomm’s announcement lists the 2+ with LTE, Snapdragon Wear 3100, Wear OS, 1 GB DDR, 8 GB storage, a 440 mAh battery, and a 1.28-inch AMOLED display. The standard Summit 2’s 340 mAh battery and 1.2-inch display come from Droid Life’s 2018 review. Do not use the 2+ specifications to describe the watch reviewed here.
