Launched in 2014, this site buys and sells pre-owned luxury watches and jewellery. Items listed undergo rigorous authentication by industry experts, and pieces can be refurbished, from fixing watch mechanisms to re-setting stones. A real-time concierge service is available so that customers can call, text or email a request and an expert will source them. Valuation reports accompany every purchase, verifying provenance, carat weight and condition. Browsing can be by brand or category, but it’s also possible to search by colour, metal, movement, condition and price. Highlights include an 18ct rose gold Moon Phase watch ($35,995) by A Lange & Söhne and a stainless-steel Sea Dweller men’s Rolex ($7,948). truefacet.com. CHRISTINA OHLY EVANS
Championing independent watchmakers is e-hub Skolorr. Its inventory of 25 brands includes some timepieces familiar to connoisseurs, but it’s the lesser-known names such as Zeitwinkel that make for the most enlightened browsing. Help is on hand in the form of a concierge service, namely from founder Sky Sit herself, who will happily walk customers through their orders. With small independent watchmakers limited in their production capabilities, making anywhere from 30 to 300 pieces a year, the site is a go-to hub for one-of-a-kinds. skolorr.com. MING LIU
Justin Gruenberg, the son of an antique jewellery dealer, founded The Keystone in 2014 with his former classmate Max Abbot. The site has a truly varied selection that will appeal to both first-time buyers and hardcore connoisseurs, taking in beloved “greatest hits” and super-rare finds from a range of brands and decades. Rolex and Patek Philippe are particularly well represented. Standouts include a Rolex Submariner ($11,000) – the line that James Bond helped make famous. thekeystone.com. MING LIU.
Benjamin Clymer founded Hodinkee as a blog on Tumblr in 2008, added the e-commerce platform in 2012 and was welcomed onto the jury of the Grand Prix d’Horlogerie de Genève in 2013. While a $175,000 vintage Rolex Paul Newman Daytona has been the most expensive watch sold on the site to date, more typical timepieces are in the $8,000 to $10,000 range, often interesting vintage steel chronographs produced by smaller brands. Many watches are accompanied by the words “sold out”, but don’t despair: shoppers are encouraged to put their name on a waiting list and will be notified when the same model comes up again. “We seek out products that we would want to buy, and we’re upfront about what we love as well as the drawbacks with each piece – whether it’s a missing lume plot or a small scratch on the lugs,” says Clymer. hodinkee.com.

Since Uniform Wares’ debut in 2009, the British watchmaker has produced elegantly pared-back and beautifully crafted timepieces. Every watch in its C and M Line collections is Swiss-made, and central to the marque is precision quartz engineering and intelligent functionality. High specs such as high-calibre Ronda or ETA premium quartz movements, plus applied batons, scratch-resistant sapphire glass and clear, anti-reflective coatings are signature components. Designed at the company’s London headquarters, these are minimal, contemporary timepieces. The C-Line has a classic silhouette (C41/PVD satin gold watch with a black leather strap, £650), while the M-Line range is a little more modern and edgy (M37 brushed-steel watch with a brown leather strap, £250). Customers can choose their own strap, and when they open the custom-made dust bag the watch is delivered in, they discover their new wristwear set to the correct time. uniformwares.com.
