Is it worth servicing a watch before you sell it?

A watch that needs work can be bought cheaper, serviced, and sold for more. Or it can soak up a service bill and weeks of waiting and come out barely ahead. The difference is doing the math before you send it to the watchmaker, not after it comes back.

What a service changes

A service affects three things in the deal at once:

• The sale price. A watch with recent, documented service can be easier to sell and may command more, because the buyer isn't pricing in an unknown repair.
• Your costs. The service itself, any parts, and anything else done at the same time come out of the deal.
• Your time. The watch is out of your hands while it's worked on, so you hold it longer. Longer holds mean more carrying cost.

A service is worth it only if the higher sale price covers the extra cost and the extra days, with your margin intact.

Run both versions

The clean way to decide is to price the watch twice: once sold as it is, and once sold after service, each with its own sale price, prep cost, and hold time. Whichever version supports the higher buy price, or the higher profit at the price you've agreed, is the better plan.

A watch that would sell for $9,000 as it is, after $150 of light prep and about 45 days. Serviced, you expect $9,800, but prep rises to $850 and the hold stretches to about 75 days. Fees are 6% plus 3% processing, your money costs 10% a year, and you want a 15% margin.

Serviced sale price needed to match selling as is

$10,013.05

Even an $800 higher sale price doesn't cover a $700 larger prep bill plus a longer hold on this watch: the as-is plan supports the higher buy price. The service only pays off if it lifts the sale past about $10,013, or if the watch simply won't sell without it.

Getting the inputs right

The decision is only as good as the three numbers behind it, and each is worth pinning down before you commit:

• The service quote. Ask the watchmaker what the work includes, what it might turn into once the watch is opened, and whether parts are original.
• The turnaround. Ask how long the watch will be away. That's the extra holding time you'll carry.
• The price difference. Look for completed sales of the same reference with and without recent service in the channel you'll sell through, and use those rather than a hunch about what service is worth.

When servicing usually makes sense

• The watch won't sell without it. If it doesn't run properly, keeps poor time, or has a visible fault, a service may be the price of getting it sold at all.
• Your buyers pay for service history. Some buyers strongly prefer a freshly serviced watch with paperwork to prove it.
• The service is cheap relative to the watch. On an expensive piece, a modest service is a small share of the deal.

When it usually doesn't

• Collectors want it untouched. For some references, original finishes and parts matter more than a fresh service, and heavy work can lower what a collector will pay.
• You need the money back quickly. A long wait at the watchmaker can cost more in carrying cost than the service adds.
• You're selling to another dealer. Many dealers would rather price the work themselves.

Buying a watch that needs service covers the same decision from the other end, when the repair is the reason the watch is cheap.
