Independent checks and a resale record for pre-owned luxury watches and bags
TL;DR Lineagely inspects pre-owned luxury watches and handbags for Indian resellers and private sellers, then issues a condition-and-history record that moves to each new owner. Resellers pay per item because a third-party check helps them sell faster. There's no NFT, and the trust comes from the inspection itself.
Fakes are routine in Indian retail. In an ASPA–CRISIL survey of 1,639 consumers across nine cities, about 35% had met a counterfeit in the past year and 89% of urban respondents said they had bought one at some point[1]. Online aggregators accounted for 53% of those purchases.
Pre-owned luxury makes this worse, because the buyer can't walk back into a brand boutique for proof. Buying guides for Indian watch buyers tell them to chase original papers, service history, a written warranty and a proper GST invoice, then find a specialist to test the piece[2]. Most sales through social media dealers and small consignment stores come with nothing but the seller's word, which is worth about as much as you'd think.
Lineagely runs inspection benches in two or three cities, staffed by trained watchmakers and leather-goods authenticators. A reseller sends an item or books a visit. The bench checks it, photographs serials and wear marks, notes condition and service state, and issues a record with a short code. The next buyer scans the code and sees the full report, plus every later inspection or service logged against the same piece. If a record is cloned then the photos and serials won't match the object in hand.
The original idea wanted a dynamic NFT for each item, and I've reframed it. India taxes gains on NFT transfers at 30% and deducts 1% TDS on each transfer[3][4], so tying every resale to a token adds tax paperwork that no watch buyer wants. A token also proves only that a record exists, not that the watch on the table matches it. A signed record held by a trusted inspector does the job.
Resellers and consignment stores pay per item, because an outside report shortens the haggle. Private sellers pay when they list on marketplaces. Buyers may pay for a pre-purchase check. As a price anchor, one global device-based authentication service costs US$139 a month (about ₹13,400) for 25 checks on its smallest plan[5]. What do Indian experts charge to inspect a watch? I found no public figure.
The Swiss watch tariff cuts under India's trade deal with EFTA began from October 2025[2], which should grow the stock of watches that later resell. Authentication device makers have made bag authentication faster and cheaper, which lowers bench cost per item. Indian resale platforms now advertise authentication as their main promise[6], so buyers are learning to ask for it.
One Indian pre-owned watch retailer puts India's pre-owned luxury watch market at about US$405 million in 2023 (about ₹3,900 Cr), rising to US$862 million by 2030[2]. One market research firm estimates the broader secondhand luxury goods market at US$751.04 million in 2025[7], but treat that as adjacent, since its method is not public. Your market is the inspection fee on a fraction of those sales, which is far smaller.
One sneaker and luxury resale marketplace authenticates items before delivery on its own platform[6]. Pre-owned watch retailers check watches they sell themselves, and independent watch service shops test watches for owners[2]. A global device maker sells authentication kits to resellers worldwide[5]. Large luxury houses issue their own digital passports through an industry blockchain consortium[8]. The gap is an independent inspector whose record any small reseller can use and any buyer can check.

The software is simple. The hard part is people - you need authenticators skilled enough that dealers accept their verdict, and you have to keep them honest when a seller offers money for a pass. One wrong call on a costly watch can end the brand.
No licence is needed to authenticate watches or bags. Your exposure is consumer law if a report misleads someone.
Building this outside India? The categories above usually have a local equivalent, so check with your own regulator.
Don't let AI give the pass or fail verdict. One wrong call on a costly watch can end the brand, so a trained authenticator signs every report.

Here's what can go south -
I think this suits a founder from watch retail or luxury resale who already knows authenticators. If you're hoping a ledger alone will create trust then it is a poor fit. First prove that 20 resellers will pay for reports every month and that buyers ask to see them.
Plan for roughly ₹60–110 L, mostly for skilled authenticators, benches in two or three cities, tools and insurance.
No. You need GST once over the threshold and DPDP compliance for owner data, and you carry consumer-law risk if a report is wrong.
Yes, the model works wherever resale is growing faster than trust. Bigger markets already have strong players, so look for one where small resellers lack a neutral inspector.

Thinking about building Lineagely or something close to it? The make-or-break work is hiring authenticators whose verdicts dealers trust and keeping them independent. If you need a hand, you know where to find me. Talk to Yash →
