Since you will incorporate some buttons, I would also add a setting so that the user can choose to disable the tilt sensor. I am sure it will work in normal daily life activities, but while playing tennis or golf and perhaps in many other situations (setting up camping), IMO it is very likely the tilt sensor will trigger a false reading and as such use battery capacity.
Those dimensions sound feasible with a rechargeable battery. Most of my designs have to fit in enclosures that were chosen by other people, and usually those people also decided the dimensions that the boards must have. With this aspect, I designed my watch cases before designing the boards. That is opposite from what people would normally do, so it may sound a bit bizarre. I only have a margin in the thickness, so it can go from 16.5mm to 17.5mm.
