Navy is the most formal colour the i10 comes in, dark without being black, and the finish most at home in a work setting. In a palette built from warm statements, navy is the one that whispers.
The platform is the shared i10: smart induction heating, LED display, 200 to 300°C, 3 to 6 minutes, 3200 mAh, leather over PC and PEEK.
What Your Hand Knows Before You Do
Spec tables measure what a device does. They do not measure what it is like to hold two hundred times a day, and that is the dimension the i10 was built for. Three things change in the hand, and each is worth stating precisely.
Grip, and the physics of warm hands. A polished or anodised metal surface is at its most slippery exactly when your hands are warmest, and in this country that is most of the year. The leather surface works the opposite way: texture that holds against skin regardless of temperature, more like the wrapped grip of good tools than the casing of electronics. The practical result is a device you handle with less deliberate care, picked up without looking, held without thinking. Owners stop noticing this within a week, which is the point.
Weight, and where it sits. 80 grams against the 83 of the aluminium i8 and i9. The number is small; the impression is larger than the number, because the softer surface spreads contact pressure where a hard shell concentrates it on edges. In a shirt pocket, the difference between a hard 83 gram object and a soft-surfaced 80 gram one is the difference between carrying a gadget and carrying a wallet.
Touch temperature, both seasons. This is the one nobody thinks of until they own it. Metal equalises with its surroundings fast: a device on an outdoor table in July is genuinely unpleasant to pick up within the hour, and one from a car in January’s air conditioning is a cold shock. Leather insulates. The i10 off the same summer table is warm, not hot; out of the same winter AC it is neutral, not cold. Over a UAE year, this is the leather’s most consistent daily gift, and no metal device in any range offers it.
None of this touches the sessions, which are the platform’s and identical across the family. What it touches is every moment around the sessions, and that is most of a device’s life in your company.
One navy-specific note on the material. Dark leather tones show patina, the gradual darkening at grip points, less than lighter ones, and navy shows it least of the five. If Brown is the colour for people who want the ageing visible, Navy is the colour for people who want the leather’s feel with the least visible change over time.
🎨 How Visibly Each Colour Ages
Patina, the grip-point deepening, lands differently across the five. Navy shows it least.
Navy quietest ageing
Purple
Green
Brown visible, and flattering
Orange most visible mellowing
Bars show relative visibility of change, not damage; on leather the change is character, not chips. Want the leather feel with the least visible change over years? That is Navy’s case in one line.

Note specific to this colour: navy reads close to black in dim indoor light and unmistakably blue in daylight. It is the i10 colour that passes most quietly in formal settings, which is worth knowing in a range that otherwise does not try to.
How to Use It
- Charge fully before first use, around 2.5 hours over USB Type-C.
- Power on and check the LED display.
- Set the working temperature, 200 to 300°C.
- Set the session time, 3 to 6 minutes.
- Insert a TEREA stick to the printed filter line.
- Start heating and wait for the ready indication.
- Use for the set duration. The session ends automatically.
- Remove and dispose of the used stick.
Compatibility
Every TEREA origin we stock: UAE, Japan, Kazakhstan, Indonesia and Armenia, plus SENTIA and other Smartcore sticks. The complete TEREA range is here. HEETS are a blade-format stick and do not work in induction devices.
Storage and Care
The i10 regime applies unchanged: under 60°C, out of sustained sun, dry or barely damp cloth, no solvents, chamber brushed occasionally when cool. The full leather guide lives on the Brown page.

Frequently Asked Questions
Does the leather body actually feel different, or is it marketing?
Different, in three measurable ways: grip that holds against warm skin where metal slips, 80 grams against 83, and a surface that never picks up the sting of a hot table or the chill of an air-conditioned car. Whether those matter to you is taste; that they exist is not.
Is the i10 harder to hold onto than a metal device?
The opposite. The textured surface grips better than anodised aluminium, especially with warm hands, which is most hands here for most of the year.
Does the leather insulate the heating chamber too?
The chamber and heat path are engineered in PC and PEEK, the same class of high-temperature materials the metal devices use internally. The leather is the outer surface your hand meets; the sessions are unaffected.
Will Navy show wear like the Brown does?
Least of the five. Dark tones absorb the grip-point darkening that shows on lighter leather, so a navy i10 changes least visibly over years of handling.
Does 3 grams of weight difference really matter?
As a number, no. Combined with the soft surface spreading pressure where hard edges concentrate it, the carried impression is lighter than the arithmetic suggests, particularly in a shirt pocket.
Can it handle being carried in a pocket with keys?
Better than a painted metal finish handles it, since leather does not chip, but a deep gouge from a sharp edge marks any material. Separate pockets remain the habit worth keeping, on this and every device.
Is the display the same as the i9’s?
No, it is the LED type the i8 uses, showing temperature, session time and battery. The i9’s sunlight-legible OLED remains that device’s advantage, and choosing the i10 means choosing feel over screen.
