Damm thing on my wrist that gets in the way and annoys me but regulations say I have to have a serviceable timepeice in the cockpit and so just in case the panal fitted one has a spring failure I wear a watch. Do I look at it.... hardly ever, but I do when it's getting close to 'home' time, mustn't be late or it's hell at home. Oh I have used it for filling in the tech log but I could equally have used a sun dial because the super modern electronic gadget on the instrument panal gives all the answers.
During my army days a watch could be used to navigate with as long as the sun was shining, really useful.
Gizmos on a watch are like the gizmos on a mobile phone, lovely to have but who uses them other than the small minority. Gadgets, gadgets are an obsession and we love them really. That's why Breitling makes them.
