Overview
The Optimus 3.0 is a GPS tracker, not a fitness watch despite its listing category, weighing 0.23 kilograms and advertised with a battery rated for more than a month per charge.
This is filed under GPS Watches, but the title and spec sheet describe a standalone tracker rather than a wrist-worn device, so it's worth treating as a tracking unit for a vehicle, asset or person rather than a smartwatch. At 0.23 kilograms it's noticeably heavier than a typical wearable, consistent with a self-contained housing built around its own battery and antenna.

- 0.23 kg
- Battery advertised over 1 month
- Brand: Optimus
Who it's for
Suits someone who wants a dedicated GPS tracking unit with a long advertised battery life rather than a wrist-worn fitness watch. Not the right pick for someone browsing this category for an actual GPS smartwatch, since this is a tracker.
Pros and cons
- Battery advertised to last over a month per charge
- Standalone tracker doesn't need to be worn
- Filed under GPS Watches despite being a tracker, which can mislead shoppers
- Heavier than a typical wrist device at 0.23 kg
Performance notes
At 0.23 kilograms this sits well outside typical wearable weight, pointing to a device built around a larger internal battery to support the month-plus runtime claimed in its title rather than a slim wrist unit.
