Lots of smartwatch and sports watch brands out there that most of us haven’t heard of. No doubt some will be gone by next year, but I’m sure people said the same of coros or Amazfit 5-10 years ago, and look where they are now. The main point is that these watches get ever more capable, and offline maps for a few tens of dollars offer amazing value for someone somewhere, and might even be a gateway to the better watches this site routinely covers.
Products like this and those from the cheaper end of Coros and Amazfit and Apple’s product ranges are examples of the ones that are squeezing Garmin at its lower end, just as Apple Watch Ultra 4 squeezes Fenix 9 Pro at the other end, at least for some type of buyers. The pattern is that Garmin’s market position is squeezed on features by sportier smartwatches and on price by cheap Chinese entrants.
Rollme’s Hero K1 puts offline maps and an LED flashlight in a rugged smartwatch for $59.99 on Rollme’s store.
- Rollme sells the watch as the Rogbid Hero K1 Military-Grade Smartwatch.
- The product listing names offline maps, an LED flashlight and a 1,200mAh battery as its headline features.
- The listed price is $59.99 USD, with shipping calculated at checkout.
- It comes in two colours, Ranger Black and Storm Grey.
What it means for athletes
A hiker on a tight budget gets a map on the wrist and a light for the walk back in the dark for less than the price of a heart rate strap. Rollme’s listing doesn’t list battery life or name the satellite systems it uses, so it cannot yet be judged on the two things that matter most on a long day out.
The Mibro AeroPace is another recent low-cost watch with offline maps, and the best hiking watch guide covers mapping watches from the established brands.
