Buying a watch collection or lot

Sometimes a seller offers everything at once: a collector downsizing, an estate, a retiring dealer clearing stock. A lot can be an excellent buy, because the seller is trading some price for the convenience of one sale. It can also hide weak pieces behind strong ones. The only reliable way to price a lot is to take it apart, value each watch on its own, and put it back together.

Value each watch on its own

A lot price is the sum of individual decisions. For each watch:

• Identify it properly. Reference, serial, condition, and accessories, recorded as you would for a single purchase.
• Estimate its resale conservatively. Use sold prices for comparable watches in comparable condition, through the channel you'd actually use.
• Estimate its prep. Collections that have been stored rather than worn often need service across the board. Price it in per watch.
• Work out a ceiling. From the resale and costs, find the most you could pay for that watch alone, using the max buy calculator with your own fees and target.

Add the ceilings together and you have the most the whole lot is worth to you. That's the top of your range, not your offer.

Allow for the weak pieces

Most collections have a spread. A few watches carry the value, some are solid sellers, and some are pieces you'd never buy individually. The weak ones matter more than they look:

• They take the same time and effort to check, photograph, list, and ship as the good ones, for a fraction of the return.
• They sell slowly, tying up capital long after the best pieces have gone.
• Their prep can exceed their value. A low-value watch needing a full service may be worth little more than its parts.

Be honest about which watches you'd rather not own, and value them at what you could realistically get for them, which may be a quick sale to another dealer.

A seller offers three watches together. Each is priced as a separate deal through a channel charging a 6% selling fee and 3% processing, with $125 of shipping and insurance out and a 15% margin target.

Watch A: resale $6,000, prep $250

$4,185.00

Watch B: resale $3,500, prep $400

$2,135.00

Watch C: resale $1,800, prep $450

$793.00

Combined ceiling for the lot

$7,113.00

Watch A carries most of the value. Watch C, once its service is paid for, leaves little room, and it will take as much handling as the others. An offer below the combined ceiling leaves a cushion for anything the inspection missed and for the slower pieces. Check watch A's number and swap in the other two.

Check every watch

The convenience of a single deal can tempt you to check the best pieces carefully and wave the rest through. Don't. Each watch in the lot needs its own inspection, its own serial record, and its own stolen-watch check. Services such as The Watch Register, which dealers pay to search by the credit, exist for exactly this.^[1] A single problem piece can create trouble for the whole purchase.

Ask how the seller came to own the collection, and whether they have receipts, papers, or service records for individual watches. A collector who kept careful records is a better source than one who can't say where half the watches came from. The pre-purchase checklist applies to each piece.

Make the offer

• Explain your number. Sellers of collections often have a figure in mind based on what they paid or what the best pieces list for. Walking them through your per-watch reasoning makes a lower offer easier to accept.
• Offer options. A price for the whole lot, and a separate price for the pieces you want most, lets the seller choose. Be ready for them to sell the best watches to you and the rest elsewhere.
• Agree what's included. Boxes, papers, extra links, straps, and tools can be spread across a collection. Make sure each goes with the right watch.
• Plan the cash. A lot ties up more capital at once than a single watch, and the weaker pieces keep it tied up. The cash flow article covers how to plan for it.

Record the purchase piece by piece

Even though you paid one price, each watch needs its own cost for your records, so you can work out profit when each one sells. A sensible approach is to split the total across the watches in proportion to the value you gave each one, and write that split down at the time. The cost basis article explains why that matters, and your accountant can confirm the method suits your situation.
