1.1 Display:

• Size:

  0.96 inches and 1.14 inches are the more common sizes in smart bracelets or small screen smartwatch models.1.09 inches, 1.28 inches, 1.3 inches, 1.4 inches, are the mainstream sizes of the round and square.2018 onwards, the large screen sizes began to be popular, like 1.54 inches, 1.69 inches, and even 2.88 inches, this larger screen size is gradually popular. size screens gradually became popular.

• Material:

  The materials of the display screen are IPS, TFT, LCD, OLED and so on. The choice of raw materials depends on the product structure and cost. Smartwatch suppliers tend to select materials with stable quality and lower cost to make the finished products more competitive in the market.

• Resolution:

  240*240dpi is a common resolution, in addition, there are 240*320 or 320*320dpi resolution, there are also 80*160dpi lower resolution, and the choice of resolution also depends on the size of the display.

• Touch type:

   There are two types of touch: full touch and single touch. Most of our smartwatches use full touch, and users get a better experience with full touch. However, there are also some products that retain single-touch, and for most users, this design also performs well.

• Cost:

  Since last year, the cost of smartwatch screens has risen dramatically, with some even reaching twice the previous cost. Generally speaking, the cost of large-size screens will be higher than that of small-size screens, however, some screens that are less frequently used and smaller in size may also cost more than large-size screens. Comparatively speaking, the most common size of the screen, the price will be lower.

1.2 CPU:

CPU is one of the key elements in the cost and quality of smartwatches, as it plays a decisive role in the quality of hardware, software, and apps. In overseas markets, we use Nordic chips, this is because we focus on mid to high end as well as high quality vertical markets. These markets require high-precision performance to guarantee remote monitoring results.

In the Chinese market, Nordic’s NRF52840 and NRF52832, MTK’s MTK2503A – ARM7 and MTK2502D, and Realtek’s 8762CW + BK3266, 8762C, RTL8762CK, RTK8762C + VC31 are among the top products.

It should be noted, however, that even with the same CPU, the quality level can vary due to other algorithmic differences between vendors. If you want to provide highly accurate data such as heart rate or SPO2, then you need to choose a high quality CPU solution.

1.3 Battery:

• Capacity:For small-sized smartwatches or smart bracelets, the battery capacity is mostly 90mah, but there are also cases of 200mah, 300mah, and even up to 650mah.
• Working time:Generally speaking, the larger the battery capacity, the longer it can be used after charging, but it also depends on the specific CPU solution. The operating time of a smartwatch varies between 1 and 30 days, depending on the solution and the number of sensors in operation. Like GPS, the Wifi function consumes a lot of power.
• Standby time:Most smartwatches have a standby time of 20 – 50 days.
• Certification:MSDS must be provided upon shipment.

1.4 Watch Case Material:

• CNC:Polished CNC cases are ideal for smartwatches and corrosion-resistant touch applications. It has a tough look that is more suited to the needs of business people. This type of case is usually used to manufacture for luxury watch brands.
• Aluminum alloy:The most common material used in mid-range smartwatches, aluminum is lightweight and elegant, and works well with any type of strap, such as silicone or leather.
• Plastic:Some customers prefer plastic cases, although some also prefer alloy cases. Plastic cases are the lightest in weight, durable and less costly than the other two case materials.
