**Shipping:** CONUS included | **Payment:** Zelle, Wire, or Crypto Up for grabs is a 1987 Tag Heuer Formula 1 ref. 381.513—a watch so cool, it literally helped save an entire industry. No biggie. While other Swiss brands were having existential crises in the '80s (RIP to the 60,000+ jobs lost during the Quartz Crisis), Tag Heuer said "If you can't beat 'em, join 'em" and dropped this bad boy. Quartz movement? Check. Swiss Made? Check. Looks that scream "I weekend at Laguna Seca"? Triple check. * **35mm case** \- Yes, it's "small" by today's dinner-plate standards, but back in '87 this was peak wrist presence. Plus, it actually fits under a shirt cuff. Revolutionary concept, I know. * **200m water resistance** \- Take it swimming, take it surfing, take it to your cousin's pool party where someone definitely does a cannonball too close to you. * **Quartz 955.412/414 movement** \- The same technology that nearly killed Swiss watchmaking... now working FOR Swiss watchmaking. The ultimate redemption arc. * **7 jewels** \- Just enough to feel fancy, not enough to feel guilty. * **18mm band** \- Strap monster potential. NATO it. Leather it. Rubber it. This watch is your oyster. This watch has been used and well cared for. It's been serviced and is now on its second battery in 28 years. The crystal is the weakest link—it's scratched. A replacement runs about $30 on eBay and takes 20 minutes to install, but I wanted to keep everything original. I've tried to capture the Jekyll and Hyde effect in the pictures. When you're looking down to check the time, you can't tell it's scratched. But turn it just right and catch the glare? You'll see what looks like somebody's kid took a farm utensil to it (that's what I envision, anyway). Look, this isn't a Daytona. It's not going to 10x in value. But it *is* a legit piece of horological history from an era when Swiss watchmaking had to adapt or die—and chose to adapt like absolute legends. Plus, you'll never have to worry about it stopping because you didn't wear it for two days. Quartz reliability, Swiss pedigree, motorsport heritage, and a price that won't make your significant other question your life choices. **Timestamp:** [https://trugrowth.notion.site/Tag-Heuer-F1-381-513-2b9acf6eb95580dd862ac850d84dd9ef](https://trugrowth.notion.site/Tag-Heuer-F1-381-513-2b9acf6eb95580dd862ac850d84dd9ef) **Price:** $410 shipped CONUS **Trades:** Absolutely!!!!
