Trading $4 to $1300 Using Watches and My Restoration Skills

Introduction

I’m Daniel. As a hobby, I run Vintage Casio Restore, a project where I restore vintage digital watches from the 80s and 90s, mostly Casio, sometimes a Swatch or two along the way. From time to time, I buy watches from online pawn shops just to see what turns up.

Last week I found a Swatch Scuba Golden Island (SDK112) from 1993 listed for 14 PLN, roughly $4, shipping included. The watch had a scratched crystal. The strap was dusty and worn. I polished the crystal and cleaned up the case, then sold it on Vinted a few days later for $25.5.

A New Project Starts

That sale gave me an idea. I already do this kind of thing on and off, buying rough watches, fixing them up, moving them along. So I decided to turn it into a proper watch flipping project, with a real goal, and track every step of it here.

Consider this an open invitation to follow along. I’ll update this post every time I complete a full round, from purchase to sale.

Why This Sounds Familiar

The idea borrows from One Red Paperclip, a project Kyle MacDonald ran back in 2005. He started with a single red paperclip and traded it for something slightly more valuable, then traded that item for the next, and so on. Fourteen trades later, he owned a house. Each step was a straight swap, one item for another, no money involved. Kyle also gave a TED Talk about the whole journey, worth a watch if you haven’t seen it.

My version runs on a different mechanic. Instead of trading watch for watch, I buy low, restore what needs fixing, and sell for a profit. Each sale funds the next purchase, and the restoration work is what pushes the value up faster than a simple swap ever could. Kyle had persistence and negotiation. I have polish, Polywatch, and a soldering iron. 🛠️

The Rules

I’m keeping the format simple so it’s easy to follow from one chapter to the next:

1. Every purchase comes from the profit of the last sale. Once the chain starts, I don’t add money from my own pocket.
2. I track every transaction in a live spreadsheet, including purchase price, shipping, restoration costs, sale price, and running total. Feel free to peek at the raw numbers anytime.
3. Restoration is fair game. Polishing crystals, replacing straps, cleaning cases, or fixing a stuck buzzer, whatever the watch actually needs.
4. The target is $1300. Once I reach it, I’ll either close the chain or set a new goal, depending on how things are going by then.
5. Each chapter covers one full cycle, from purchase to sale. I’ll post progress shots on my Instagram between chapters, but this post is where the full record lives, updated every time I complete a round.
6. All USD figures use a fixed exchange rate of 3.69 PLN per $1, set at the start of this project, rounded to the nearest $0.50 for readability. That keeps the dollar numbers consistent as the chain grows, instead of drifting with daily exchange rate swings.

Round 1 – How the ‘Watch Trade Project’ started?

One day I found the Swatch Scuba Golden Island (SDK112) on a Polish online pawn shop. The watch dates back to 1993. The listing itself called it a generic “Swatch Swiss two-tone watch,” no model name, no mention of “Golden Island,” just a placeholder title. The item cost 9 PLN. Shipping added 5 PLN. The total came to 14 PLN, about $4.

I picked the cheapest shipping option available. The watch wasn’t time-sensitive. The package could take a few extra days. Every zloty counts on a budget this tight. 📦

The watch arrived in decent condition. It worked. The original strap had survived in reasonably good shape. I polished the crystal, polished the case, and cleaned out the crevices under the strap mounting, the spots that collect years of grime and get skipped in a quick clean. 🛠️

I bought the watch on May 7th. I listed it on Vinted soon after. The listing sat for a while. I knew someone would buy it eventually, a decent-condition original strap and a clean case are exactly what Vinted buyers look for on a piece like this. The sale finally came through on June 29th.

It sold for 95 PLN, about $25.5.

Purchase: 9 PLN item + 5 PLN shipping = 14 PLN total (~$4.00)
Sale price: 95 PLN (~$25.50), sold on Vinted
Profit: 81 PLN (~$21.50)
Return on this watch: ~579% (nearly 6.8x the purchase price)

Running total: 95 PLN / $25.50 of $1,300 (1.9% of the goal)

What’s Next

95 PLN isn’t a huge budget yet, so I’m not rushing into the next purchase. I’m keeping an eye out for the right opportunity instead of grabbing the first listing I see. My thinking: once the budget hits 400 to 600 PLN, the selection opens up considerably, better models, better condition, more room to actually improve something instead of just cleaning it up. Until then, I’ll wait and watch the listings.

Round 2: A Dead Casio Comes Back to Life

I found the Casio AQ-307 at a flea market, sitting on a table full of old junk. I asked the price on the spot. The seller said 10 PLN. I paid and walked off with it.

The watch showed no signs of life when I picked it up. Neither the analog hands nor the digital display responded. At that price, the risk felt worth taking.

Back at my desk, I swapped the battery. Both modules came back to life, the analog hands started moving and the digital display lit up. That’s a good sign on any AQ-series Casio, since it means the movement itself is healthy and the fault was just a dead cell.

I took the whole watch apart. I cleaned every component, removed the scratches from the caseback and bracelet, polished glass and restored the satin finish across both. 🛠️

The watch was in average condition even after the work, nothing museum-grade, so I kept my price expectations modest. I listed it on Vinted and sold it for 70 PLN.

Purchase: 10 PLN, bought in person, no shipping (~$2.50)
Sale price: 70 PLN (~$19.00), sold on Vinted
Profit: 60 PLN (~$16.50)
Return on this watch: ~600% (7x the purchase price)

Running total: 155 PLN / $42 of $1,300 (3.1% of the goal)

What’s Next

A modest flip, but it moves the budget in the right direction. With 155 PLN (~$42) now on hand, I have more room to look for something much more expensive. The bigger the budget gets, the more the selection opens up.

Round 3: A Scratched-Up Crystal Gets a Second Chance

I found the Casio Edifice EFV-580 on an online pawn shop. The listing showed a heavily scratched crystal and plenty of grime, which kept the price low: 85 PLN for the watch, plus 15 PLN for courier shipping. The total came to 100 PLN.

The watch arrived exactly as described. I put in a fresh battery first, just to check the movement. It ran. That confirmed the core was fine, everything else was cosmetic.

The case, bracelet, and clasp had years of grime packed into every crevice. I disassembled the watch and ran the parts through an ultrasonic cleaner to get into spots a brush can’t reach. Since the case and bracelet are steel, I also went ahead with a full bracelet regeneration: removing scratches and restoring the original satin finish. 🛠️

The scratched-up crystal was the last piece. I pulled out the old glass, measured the diameter and thickness, and ordered a matching replacement online for 19 PLN. Prime shipping meant no extra cost there. Once the new crystal arrived, I pressed it into place and reassembled the watch. That one swap turned a tired-looking piece into something that looked almost brand new. ✨

I listed the watch on Vinted soon after. The sale came through not long after that.

It sold for 200 PLN.

Purchase: 85 PLN item + 15 PLN shipping + 19 PLN replacement crystal = 119 PLN total (~$32)
Work done: Battery test, full disassembly, ultrasonic cleaning, bracelet regeneration (scratch removal and satin restoration), crystal replacement
Sale price: 200 PLN (~$54), sold on Vinted
Profit: 81 PLN (~$22)
Return on this watch: ~68% (1.68x the purchase price)

Running total: 236 PLN / $64 of $1,300 (4.7% of the goal)

What’s Next

This round cost more than the first two combined, largely because of shipping and the replacement crystal, but it also returned the highest profit in raw PLN so far. With 236 PLN (~$64) now on hand, the budget is starting to open up real options: better modules, more interesting complications, maybe something with a bit more collector appeal than a straightforward Edifice.
