Microsoft Windows 95 desktop for Pebble Classic & Pebble Steel. The time is displayed in the system tray as usual. 

The start menu may look too white in the screenshot, but that trademark grey start menu looks great on the watch itself!

A replica of the Nokia 3310 screen, with the time in the top right corner. The network & battery icons are just for show, and obviously the menu is non-functional. But it's perfect for anyone else who got their first phone in 1998!

Black & White only, as it was designed for classic pebble.
