Why you'll like it

• 1.43" AMOLED display, 466×466 — sharp, high-contrast screen in a metal case
• Zinc alloy body and stainless steel band — solid metal construction throughout
• Rotary encoder crown — physical navigation control without touchscreen interaction
• 3ATM water resistance — splash and handwash resistant
• Two straps included — silicone and solid steel band in the box

Designed for everyday smart watch use

The IO34 combines a zinc alloy metal body with a 1.43-inch AMOLED display and a rotary encoder crown for physical navigation — useful when the display is wet or gloves are worn. The 3ATM water resistance rating covers everyday splashes and handwashing; it is not a swimming or submersion rating. Bluetooth connectivity links the IO34 to a companion app for GPS positioning (via the phone), call notifications and activity tracking. The heart rate sensor (VC30F-S) and LIS2DOCTR accelerometer log movement and heart rate data to the app. The 300mAh battery provides 4 to 6 days with Bluetooth active. Two straps — a silicone strap and a solid stainless steel band — are included. The disassembly tool allows swap between them. Curated by Aetheo for everyday smart watch use.

Key features

1.43" AMOLED display — 466×466 resolution

The IO34 uses a 1.43-inch AMOLED panel at 466×466 resolution. AMOLED provides high contrast and sharp text rendition in a compact watch display. The AD7012 main controller drives the display and core watch functions; 128Mb of onboard storage holds the watch operating data.

Zinc alloy body, stainless steel band, rotary encoder

The watch body is zinc alloy — a rigid metal construction. The solid band option included in the box is stainless steel (SUS), providing a fully metal watch presentation. A silicone strap is also included for everyday or active wear. The rotary encoder crown allows physical scroll and navigation input on the watch body without touchscreen interaction. The disassembly tool included enables strap swapping.

3ATM water resistance — 30m

The IO34 is rated 3ATM (30 metres static pressure). This covers everyday water exposure — splashes, handwashing and light rain. It is not rated for swimming, showering under pressure or submersion. Do not operate the rotary encoder crown or press buttons while the watch is submerged. 3ATM is not a swimming or diving certification.

300mAh battery — 4–6 days use, magnetic charging

The 300mAh battery provides 4 to 6 days of use with Bluetooth active depending on feature usage. Active GPS-linked tracking and continuous sensor polling reduce battery life toward the lower end of the range. Standby time is 10 to 15 days. Charging is via magnetic contact at approximately 3 hours from empty. A charging cable is included.

App-linked GPS, calling, heart rate sensor

GPS positioning is app-linked — the IO34 uses the connected smartphone's GPS rather than a built-in GPS module. Calling support is via Bluetooth connection to the phone, enabling call answer and reject from the watch. The VC30F-S optical chip provides heart rate data and the LIS2DOCTR accelerometer tracks movement — both log to the companion app for activity tracking features. Bluetooth version is not explicitly stated in source documentation.

Best for

• Those who want a metal-body smart watch with AMOLED display and rotary encoder
• Everyday use with 3ATM splash and handwash resistance
• Users who want both a silicone strap and a solid steel band included in the box
• App-linked GPS tracking and call management via Bluetooth
• CE certified smart watch with 4–6 day battery life
