Mechanism Big
I need a countdown timer too small Satellite Digital, which may take months?

I make a box for jewelry delay time my girlfriend and I can not find what you need. There are many digital countdowns, but are too high. It must be very low. As the size of a cookie. Do not even need show only the timing mechanism. You must also have some kind of alarm or action when it reaches zero so it can trigger the open box. Moreover, countdown to be about 6 weeks and light a small battery. Any ideas on where to look or how can I do? Thanks
