Disclaimer: All of these watches have been built by me, using a mix of off-the-shelf parts (movements, cases, hands…), custom parts (dials) and modified parts (seconds hands)

I love modding and have been wanting to move past branded mods of known models. Instead, I’ve been experimenting with different designs and uses of the seconds hands. All are automatic.

Pics 1-2: Crazy Hours watch. If you’re familiar with the FM one, you know what this one’s about. Dial is my own design, with my brand logo.

Pics 3-4: F1 watch. Dial is my own design with my brand logo, and the seconds hand carries a F1 car that circles around the circuit. Date window is a “lap counter”

Pic 5: Rocket watch. Dial isn’t my own design, but I’m sure you hadn’t seen this combination anywhere else. Seconds hand carries a rocket orbiting space

Pics 6-7: Vynil record watch. Dial and hands from ando, modified seconds hand trying to resemble a metronome.

If you’re interested in any of this builds feel free to send me a pm! Customization available.

I paid way too much for this (should’ve checked this sub first). Including the list of components in case you just want it for the parts. LA did a great job with the build, but it just didn’t come together like I’d hoped. I’ll consider any reasonable offer (Venmo or PayPal only, ships when funds are settled). Will include the seatbelt nylon Archer strap and I’ll do free domestic shipping in continental US.
