/diy/ - Do It Yourself

Bought meself a terrorist watch (f-91w).
The backlight is shitty, I thought about resoldering the led on the watch's PCB so it faces more towards the display to give more light.
Since I will be desoldering the LED anyways I had an idea to replace the stock LED which is standard green with something else since I really liked amber-coloured backlight on one of my shitty casio watches I had a few years ago.

Then I encountered a problem.
F-91W is powered by a CR2016 battery which have nominal voltage of 3V and that's what I assume the watch's electric pixie sorters are running at. The stock green LED (SMD component called 0805 whatever that means) is rated for 2.8-2.9V according to most offerings on ebay which is well within the ballpark number of 3V of the watch's battery and seems to work fine.
Amber 0805 SMD LED is rated for 2-2.2V. How big of a problem it is if the LED is never powered for more than 10 seconds at a time?

Is it going to have a massively shorter lifespan because of me running it at a significantly higher voltage than it's rating or is it just going to blow up as soon as I press the button?
Also is it going to be a lot brighter than the stock one?

Please halp, I'm a drooling retard when it comes to this stuff and despite the terrorist watch being a cheap piece of shit I don't really want to spend another 12 bucks for a replacement when I fuck this one up.
