So you are looking for a wristwatch that stands out? The Cyber VFD Watch is well worth a look. It uses IVL2-7\5 VFD tubes to display the time. It features a 11.5mm thick case and large battery. Cyber can show 4 digits at once, so it supports 12/24 hour time formats.
You can order Cyber in two colors with plastic and metal case on Kickstarter at this time.
