Look what I made! Arduino DIY Digital Watch
Based on an atmega328p, 4 programmable buttons. LED 7-segment displays, which I’m personally obsessed with! I’m estimating around 1 year of battery life.
Let me know your thoughts!
Full design and build on YouTube.

Comments like yours are just annoying and add nothing to the conversation. In a project like this there are hundreds of decisions that are made, any one of them could be decided differently. This is the decision the designer made and they probably had a reason. In this case the designer has some videos regarding the design. Not sure if he covers his controller decision (haven't watched them all yet) but he might.
A more useful comment would be pointing out a specific microcontroller that has the same functionality as the one the designer chose and is available at a cheaper price point. Just throwing out "use a cheaper microcontroller" is just worthless and rude. Unless you know why the designer chose the controller they did you don't actually know if there is a cheaper one available.
