It pays for itself in 6–17 weeks.

How is this calculated?

You charge $20 for the water-resistance test when you replace a battery (assumption: in the US a battery alone starts at $20 and reseal plus pressure test is $45–60, Long's Jewelers; in the UK from £10 versus from £40, Aspens Jewellers; that gap includes the gasket, so we count only $20) on 2–6 watches a week (assumption), 48 weeks a year, minus about 5 min of counter time at $45/h ($4) per test. Returns of flooded watches avoided are not counted.

Each sale: Equip a jewelry store with its tester, set up · you charge ≈ $790 · it costs you ≈ $440

Revenue
≈ $79,000
Costs
≈ $43,900
Profit
≈ $35,100
How is this calculated?

You charge $790 for the assembled tester, setup and training (assumption); it costs you the unit ($350), 1.5 h at $45 and $20 of travel (assumption). The store can buy it directly: what you charge on top is your setup and training. Costs = what each sale costs you × sales + the licence (and any reusable kit), once. Your time is already paid at $45/h inside the costs.

Estimates with the assumptions in plain sight, not promises: your numbers depend on your business, your area and your prices. Profit before taxes, without subtracting client acquisition, payment fees, travel (unless stated), warranties, support or servers. 1,000 sales is a theoretical scale, not a forecast: it would need staff and structure not counted here.

The problem

You change the battery, and days later it comes back with water inside

Changing a battery opens the case. If the gasket seats badly, the watch fogs up within days and the complaint lands on your shop. To check, both options are bad: the benchmark dry tester lists at $1,295 (Elma Leak Controller 2000, Sept Tools) and leaves no report, and a cheap water tester wets the customer's watch if it fails. Meanwhile, the pressure test you could charge for either goes undone or goes free.

How it works

The Watch Leak Tester is a bell jar on a base that fits on your counter. Put the watch under it, press one button, and in a little over a minute the app says "Sealed", "Leak" or "Unclear", with nothing getting wet. Every test is saved with its date, the watch and the result, and a test report comes out to print or send with the receipt. It is a dry test, not a certificate or a guarantee for immersion: the call stays yours.

  1. Set the watch under the bell and press the button.
  2. In a little over a minute the app says "Sealed", "Leak" or "Unclear".
  3. Print the test report and staple it to the receipt.

FAQ

Will it work on every watch that comes across my counter?

On watches with an intact crystal, a closed caseback and the crown pushed in or screwed down. Vintage watches or ones with a glued crystal use the Delicate mode; never test a watch with a cracked crystal or an open back. Some very rigid cases or very large leaks may come back as "inconclusive": that's your cue to check the gaskets.

Does the report mean my customer can swim with the watch?

No. It's a dry test report: it shows whether the case was sealed on the day of the test. It is not a certification, it doesn't guarantee submersion or any depth rating, and it doesn't replace the manufacturer's water-resistance test.

Does it get the customer's watch wet or put it at risk?

No water involved: the test is dry and takes just over a minute, one watch at a time. If it reads "leak", the watch is still dry and you can replace the gasket before handing it back.

What's on the report, and how do I give it to the customer?

The date, the watch (photo and the customer's reference) and the result, with your store's logo and address. It comes out as a PDF to email or print with the receipt; the printer isn't included (a network or Bluetooth receipt printer works, or a regular one). Every test is saved in the customer's and the watch's history.

What does it cost in total, and when do I get it?

One price: $190, one-off, for every use. The tester (base and dome) is bought separately: about $290–350, indicative, and we tell you what to buy and where. You also need a phone or tablet on WiFi and a power outlet at the counter. You get the licence and download link within 12 hours; if it doesn't arrive in time, you get your money back.

Do updates cost extra?

No. Periodic updates are included, with no subscription. We email you about each new version and you install it whenever it suits you.

I equip jewelry and watch stores: can I set it up for my clients?

Yes. You can set it up on the counter of as many stores as you like and charge whatever you decide for the unit, setup and training. The tester is bought separately. What you can't do is sell or hand over the software itself: copies, downloads or the installer for someone else to install on their own. You charge for your work, not for copies of the software.

What support is included?

Written support by email for building the tester, setting it up at your counter and the report, plus a phone call whenever you need one.
