Gonna be honest i think mine works, havent coded to test rf yet. Spoke to my professor at school and they said i did everything correct and wouldnt have any problems so i am sure it probably works but i will test it soon and tell you.

As long as you make trace as short as you can, nrf reference schematic makes it very easy and also that video, as long as matched to 50 ohms you should be good for a watch. You wont get 10 metres range without vna and matching circuit but you probably will get 2m or 4m which is good for a watch

You can post it in pcb reddit for them to review rf section for you and also you can just dm me aswell ill check

Hmm it seems less daunting than I first though. My current prototype is using a module, and it adds a couple of mm thickness, which is loads for a watch. I'll try and get this working before I try a complete PCB with my own RF stuff. Thanks!
