I'm building a digital watch and I need some thin as fuck 7-digit displays, anyone know where I can find some?
Preferrably pretty cheap.
I've been looking at ones like in pic, but they are a little on the small side.

Is that a bomb?!

>7-digit
Do you mean 7 segment?
If the thickness of the display in your pic is ok, then you can get ordinary single digit SMD displays with comparable thickness.
There's also the option of building segments from 0402 size LEDs. Pic related.
If a fancy alphanumeric display is ok, some of them are pretty easy to open so that you'll have a PCB with a bunch of bonded LEDs. They're less than 1.5mm thick.

Fuck off.

>7-segment
Yep, durp.

It's not strictly the thickness, but rather the aesthetics. Having thick blocky displays on the clockface would look odd. SMD displays look promising though.

Those alphanumeric ones look really nice, but kinda pricy, I'm using only parts I scrounged from my electronics club (except for the MCU) and it's mostly for learning anyways.

If you can only find ones that small, why not experiment with a magnifying lens for the crystal?

Post it in the watch thread in /g/ when you're done.

The one I'm building is kinda barebones, and I'm only using really cheap stuff, I settled on thin 3x7-segment (hours will be shown in hex) in an SMD package I got for 50cent.

If I make another one it will definitely use some nice alphanumerical displays and be decked out with more features.

Bubble display or HP QDSP-6064.
Ebay for example.

Looks similar to a VFD's grid when running at a higher voltage, with some of them in an 8 shape you could have a big digit.
