When a brand, distributor, corporate buyer, or cross-border e-commerce seller wants to develop a custom smartwatch, they soon discover that the entire process—from concept to mass production—is far more complex than expected.

To make this clear and practical, this article uses a Muslim Smartwatch as a complete real-world example to demonstrate every step of a true OEM/ODM project.

1. Why the Muslim Smartwatch Is a Perfect ODM Case?

The Muslim market has 1.9 billion global users, yet only few manufacturers can provide a smartwatch that integrates:

• Accurate Quran content
• Islamic prayer features
• Religious UI
• Multi-language support
• A synchronized mobile app

This product represents a typical “industry-specific deep customization smartwatch”, which best showcases engineering capability.

Islamic religious features

• Built-in Quran player (114 Surahs)
• Prayer time reminders
• Qibla compass
• 99 Names of Allah
• Hijri calendar and festival reminders
• Tasbih counter (digital dhikr)

Smartwatch features

• Bluetooth calling
• Voice control
• Heart rate / blood oxygen / sleep monitoring
• Step count, calories, mileage
• Women’s health tracking
• Weather, music control
• Notifications (WhatsApp, SMS, Facebook, etc.)
• Custom watch faces

APP: iMuslim Pro

Core hardware

• Chipset: JL7012F6
• Screen: 2.0" 320×385 IPS full touch
• Memory: 128M Flash + 4GB
• Sensors: LC11S heart rate
• Battery: 320mAh
• Wireless: BT5.0/BT3.0

A smartwatch like this requires algorithm design, religious content integration, UI customization, APP development, multi-language support, and sophisticated sensor calibration.

2. Why Do Companies Choose Smartwatch OEM/ODM?

This content aligns with Article #1 and #2, creating a complete SEO topic cluster.

Brands choose OEM/ODM when they need:

• A fully customized smartwatch
• A dedicated product for a specific audience (e.g., Muslim users)
• Corporate gift smartwatches
• Unique SKUs for Amazon, TikTok, Shopee, Temu, Daraz, etc.
• A reliable and scalable supply chain

This is exactly the strength of Shenzhen Geyan Technology.
