We don't just build fancy watches. We also offer light servicing such as degaussing, bracelet sizing, gasket replacement, battery changes (if applicable), and more.

In case you were wondering, our watches aren't scared of a little water. Every Casa Nera piece is designed to be used, and is certified to no less than 100m of water resistance unless stated otherwise.

Go touch grass, get some sun, and enjoy some pool time this holiday weekend. There's plenty of things to worry about, taking your watch for a swim shouldn't be one of them.

I wanted to do something fun for the page and give someone the chance to get a custom built watch for a whopping $20.

Here’s how it works:

• 20 total spots available
• $20 per spot
• One winner receives a custom watch hand built to their specifications, examples of recent builds below
• If a contestant chooses to place another $20 on their entry, your build will also include a FREE watch display/winding case if selected as the winner.

Once all 20 spots are filled, entries close immediately and the post will be marked *CLOSED* with a timestamp in the comments. Any payments sent after closing will be refunded.

I’ll go live at 7pm the day entries close and randomly draw the winner.

After the drawing, I’ll contact the winner directly to discuss build details. If the winner does not respond within 48hrs, their name will be removed and another winner will be drawn from the same contestant pool.

Current turnaround time is approximately 2–4 weeks. If you’re outside the Wichita area, shipping is on me!

Want the contest to close sooner and get your build faster? Share this post so we can get this in front of more eyes and get it closed sooner!

Available spots will be updated in the comments as they’re claimed.

Payment options:
Venmo: Jkeating93
CashApp: $polywerx

(Payment disclaimer: accounts for Casa Nera Instruments are still being set up, using my personal & separate business accounts temporarily)

Roughly 25% of the American workforce consists of trade workers. We use tools, and most of the time, we're not very gentle with them. We need tools that not only meet the demands of daily abuse, but exceed them. What's on your wrist should be no different, looking cool is just an added bonus.
