**(If I don't receive full answers to all the questions below, there will be no deal)**

Could you recommend 5 different smartwatch models that include the following features: Heart rate sensor, blood pressure sensor, body temperature sensor, WiFi, accurate GPS, 4G SIM slot, and the ability to receive notifications? I plan to purchase these for testing in our environment.

We would like to request a sample to evaluate before deciding on the quantity. We cannot estimate the quantity at this stage without thoroughly testing both the server and the watch.

Let me know if you need any specific information or resources from my side, such as a domain name or other requirements, to proceed with modifications. Please also provide the communication protocol documentation and the SDK for the recommended watches.

Could you confirm if it's possible to customize these smartwatches to send GPS data to one domain and vital signs (heart rate, blood pressure, body temperature) to another domain? Could you also provide the data format, along with an example of the structure of the data that will be sent?

Once we've completed testing and developed our APP, would it be possible to explore potential modifications, such as removing the camera, disabling the mic and speakers, disabling call functions, or even developing a custom model?

How flexible are the customization options for firmware or software updates post-purchase? Can these updates be managed remotely?

Are there specific regulatory certifications (e. G., CE, FCC) or industry standards the watches comply with, especially for health monitoring features?

What are the scalability options for mass production if we decide to proceed after successful testing?
