What We Manufacture
We are a smartwatch manufacturer supplying both private-label form factors and project-grade devices that integrate with your app or platform.
Platform Advantage
Our BLE master controller is nRF52840—chosen for stability and ultra-low power, giving predictable budgets even when paired with long-range radios.
Enclosure & Tooling
ID/MD, mold creation, finishes (painting/electroplating/anodizing), strap options including anti-tamper structures when needed.
Displays & Power
Durable TFT and memory-in-pixel (MIP) for outdoor readability and low power; optional E-INK/transflective for extreme battery goals. Magnetic/pogo/batch charging.
Electronics & Sensors
PPG/SpO₂, skin temperature, ECG, EDA/GSR, 3-axis accelerometer (raw), optional gyroscope (e.g., X5), barometer, speaker/buzzer (e.g., HM01 voice prompts).
Firmware & App Support
RTOS based variants with OTA/DFU
SDKs, data formats, and platform integration guidance
Connectivity Options
BLE for phone-paired experiences & low-power data sync
CAT-1/LTE-M for voice/SOS/stand-alone data in the field
LoRaWAN for long-range, low-power telemetry and location
UWB/GPS for precise indoor/outdoor positioning
Choose Your Path
Connectivity & Architecture (BLE First, Options Beyond)
Every model supports BLE by default, with broadcast to gateways/base stations in addition to phone pairing via SDK. For projects requiring more
LoRaWAN
long-range, low-power telemetry and location; band selection from the watch menu; downlink control and remote settings.
UWB (J3 variant)
high-precision indoor ranging for customers who need sub-meter accuracy.
Cellular roadmap
CAT-1 (stand-alone data/voice/SOS) in development; CAT-M/NB-IoT under R&D.
Custom transports
Feasibility for Sigfox, Wi-Fi, and LoRa P2P messaging where networks are unavailable.
Project-Grade Options (For Enterprise/IoT)
Designed for customers who need data ownership and integration with gateways/platforms.
Raw signals
PPG raw, 3-axis accel raw, and on X5 also gyroscope raw—so your team can build precise analytics.
Beacons & indoor positioning
Watches scan/list beacon IDs & RSSI for improved indoor accuracy; can fuse with GPS when needed.
Protocols & SDKs
BLE broadcasting protocol, LoRaWAN protocol (uplink/downlink), and Android SDK with examples.
Firmware openness
Optional open device via J-Link (blank firmware) for deep custom work (no source code). We can also open specific modules only—e.g., UWB ranging while we retain BLE—so you can insert your stack.
Design & Mechanics
ID/MD from enclosure to strap systems; anti-tamper straps with alert triggers for supervision use cases. Ruggedization for dust/sand ingress, IP67/68, drop and vibration.
UI & Algorithms
Add/remove stock UI elements or embed your own UI assets. Implement your specific algorithms or integrate your compiled models for on-device feedback (e.g., haptics).
Electronics
Add/remove sensors per program (e.g., gas detection). Battery capacity and charging approach (pogo/magnetic/batch).
Data Transport & Protocols
Today: BLE + optional LoRaWAN; roadmap: CAT-1, CAT-M/NB-IoT. Payload adaptation so the watch can talk to your existing devices/platforms. LoRa P2P for direct device-to-device messaging where networks are unavailable.
Manufacturing Capabilities & Quality
Capacity: 3 SMT lines / 4 assembly lines; up to 10,00k units/month.
Process: IQC → SMT → Assembly → Aging → OQC, with serialized records and retain samples.
Reliability tests: high/low temp, vibration, drop, salt-fog, dust/sand, waterproof (IP67/68).
Requirements & feasibility (D0–D7)
→ scope, sensors, connectivity, ID/MD brief
DFM & BOM confirmation (1–2 wks)
→ materials, tooling plan, test plan
Samples (2–4 wks)
→ appearance & functional samples, basic lab checks
Pilot build (4–6 wks)
→ small batch, reliability & field validation
Mass production (8–12 wks)
→ OQC, packing, shipping documentation

Quality control and assurance measures
Quality is central to iSmarch’s values. Our dedicated quality control team adheres to strict guidelines and procedures, monitoring every manufacturing stage. In addition to routine inspections, we conduct in-depth testing on each smartwatch to verify performance, battery life, and durability. This comprehensive approach ensures our smartwatches meet or exceed industry standards.
