Description
The Colmi Smartwatches I28ULTRA-SB comes from a brand that has built its name on feature-rich smartwatches, and this model pairs a round case with a 1.43 inch AMOLED display and a silicone strap secured by a pin buckle.
Case & crystal
The case is round, a familiar shape taken from traditional watchmaking, and it frames a 1.43 inch AMOLED display. That screen is the defining feature of the I28ULTRA-SB, and it sits at the centre of everything the watch does.
Dial
The display has a 466 x 466 resolution, so the digital watch face renders sharply across its full round surface. The face combines digital readouts with analogue-style hands, giving the familiar reading of a conventional dial alongside live data. Heart rate and step data appear directly on the face, so the key figures are visible at a glance without opening a menu.
Movement
This is a smartwatch rather than a mechanical or quartz watch, so it has no beat rate or power reserve in the traditional sense. Its functions are an alarm, a stopwatch, a step counter and heart rate monitoring. The alarm and stopwatch cover daily timekeeping, while the step counter and heart rate function track activity through the day.
Bracelet & fit
The band is a silicone strap fastened with a pin buckle. A pin buckle lets you choose the hole that suits your wrist, and silicone is a soft, flexible strap material that suits regular, close-to-the-skin wear.
On the wrist
With a round case and a 1.43 inch display, the I28ULTRA-SB gives a clear, readable face on the wrist. The silicone strap and activity-tracking functions make it a natural fit for everyday wear, from the office to time spent on the move. Heart rate and step data on the face suit anyone who likes to monitor their routine. Browse the full Colmi Smartwatches watches range, or compare it with all watches in our collection.
