Hello Dear,
We are a team of experts with a cumulative experience of over 50 years in the field of embedded systems, electronics, product development, prototyping and Engineering. Our experts have hands on experience with 8-bit, 16-bit and 32-bit architectures developing ultra-low power designs with complex computations. We have the development tools for almost all families of MCUs. We work in Smart Meters, Wireless, Telecommunication and Automotive.
I have checked the details of your work and shared the same with my team. Believe me we did similar works for many client. We have the inventory for such a smart watch in house. This clock must use BTLE (like CC2540) along with a colored TFT round display (like 1.22'' diameter) along with miniature vibration motor and a beeper. I would charge you US$ 500 for x2 workable samples. This includes the following milestone
1) Schematics Design and PCB layout ---------------------------------------- 200$
2) Sample preparation, BOM costing and PCB fabrication --------- 150$
3) Firmware Development ------------------------------------------------------------ 100$
4) Shipment ---------------------------------------------------------------------------------- 50$
If you have any question please feel free to ask.
Regards
Ch
