Hermès does not describe itself as a watchmaker. The maison has, for the last half-century, made watches — quietly, in La Chaux-de-Fonds, with movements from Vaucher and Manufacture Hermès, and with the same discipline it applies to a Sellier Kelly. But it does not lead its own conversation with them. Which is precisely why they are interesting.
At a moment when the wristwatch has become a currency of self-presentation — chronographs on Substack, GMTs at brunch — Hermès watches sit deliberately outside the discourse. They are worn by women (and men) who have already made the point. The Kelly Watch on a leather cordon, the Heure H at the wrist of a Parisian editor, the Cape Cod on the arm of a novelist at Wilton's: these are watches for people who do not need one to explain them.
This guide covers the four current pillars of Hermès horology as of 2026 — Kelly Watch, Heure H, Cape Cod, and Arceau — with sizing, movement notes, and honest 2026 pricing in London. At the end you'll find a comparison table, an FAQ, and links to the pieces currently in the JULL Knightsbridge stock room.
The Kelly Watch: bag first, watch second
The Kelly Watch is Hermès's most literal object: a Kelly bag miniaturised into a bracelet. Introduced in 1975 and designed under Jean-René Bousquet-Cavagnac, it took the Kelly's Sellier flap, sangles, cadenas and clochette and shrank them into a wrist-scale composition. The face of the watch sits behind the flap; opening the padlock is what tells you the time.
It is a small, private joke. And, like most Hermès small jokes, it has become one of the most recognisable objects in the house's catalogue.
The Kelly Watch is quartz. It has always been quartz. Purists sometimes register disappointment on this point, but the Kelly Watch is not sold as a horological instrument — it is sold as an accessory in the strict French sense of the word. It exists in three sizes:
- **Kelly Watch Mini** — 16mm case, thin strap, the size most requested at JULL and the version most flattering under a cuff. - **Kelly Watch Small** — 20mm case, a fraction more legible from across a room. - **Kelly Watch Medium** — 25mm case, worn as a statement rather than jewellery.
The strap options are where a Kelly Watch acquires its identity. Around a slim epsom or box calf strap in a house colour — Rouge H, Étoupe, Vert Cypres — it reads as a bracelet with a secret. On the double-tour (double-wrap) leather it becomes almost sculptural. Steel Kelly Watches with a full diamond pavé bezel and dial — of which we currently have two in the Knightsbridge showroom — are a category unto themselves: worn without an evening bag, they are the evening bag.
Retail on a new steel Kelly Watch Mini in 2026 is approximately £5,100. A gold Kelly Watch with palladium hardware sits closer to £11,500. Full-diamond Kelly Watches in steel with mother-of-pearl dial, the version [we currently stock](https://byjull.com/shop/hermes-kelly-watch-mini-steel-diamonds-mini-16mm), retail at around £13,500 new. On the secondary market, the diamond-pavé versions hold value more consistently than the plain-steel entry pieces, because Hermès does not run large-scale advertising on diamond releases and buyers who want them tend to know exactly why they want them.
Heure H: the H that started a rebrand
If the Kelly Watch is a Kelly bag, the Heure H is a monogram. Launched in 1996 by the in-house designer Philippe Mouquet, the Heure H arrived at almost exactly the moment the maison, under Jean-Louis Dumas, was consolidating its visual language around a single letter. The watch's case is that letter, cut out of steel or gold and set on the wrist as a piece of typography.
Twenty years on, the Heure H has become the entry point to Hermès horology for a particular kind of buyer: the woman who wants an Hermès on her wrist without wanting it to look like she has staged an Hermès moment. It is quieter than a Cartier Tank, simpler than a Chanel Première, and — because it is Hermès — completely uninterested in explaining itself.
The Heure H comes in four sizes. In our experience the two smaller sizes account for the overwhelming majority of demand:
- **Heure H Mini** — 17.2 × 22mm, quartz. The version we currently hold in three configurations at the showroom. - **Heure H Small** — 21 × 25mm, quartz. Legible from a metre away. - **Heure H Medium** — 25 × 30mm, quartz. Reads clearly across a table. - **Heure H Grand** — 34 × 34mm, mechanical automatic in some references, less common on the secondary market.
Retail on a new Heure H Mini in steel with a leather strap sits at approximately £2,450 in 2026. In yellow gold with palladium hardware — one of the more difficult combinations to source — the number rises to roughly £8,000. A steel mini with a diamond bezel lives around £5,800.
We currently hold three Heure H pieces, all in the smaller cases, at [our jewellery counter](https://byjull.com/shop/jewellery): a steel mini, a mini in gold with GHW, and a small in gold with PHW. The gold cases are notable because they are increasingly hard to find at boutique — Hermès's gold Heure H allocations have contracted since 2024, and clients who once bought the steel now enquire directly about the gold at pre-owned houses like ours.
Cape Cod: Henri d'Origny's rectangle
The Cape Cod is the watch you either understand immediately or do not understand at all. Designed by Henri d'Origny in 1991, it is rectangular where every other Hermès watch is rounded, and it is worn double-wrapped where every other Hermès watch is worn single. It looks, at rest, like a stirrup — which is d'Origny's private joke on the maison's saddler origin.
There are three sizes: Cape Cod PM (23 × 23mm), Cape Cod GM (29 × 29mm), Cape Cod TGM (33 × 33mm). Movement is quartz in the base models and mechanical automatic in the higher-tier references, including some rare tourbillon variants that surface at auction rather than at showrooms.
Retail on a new Cape Cod in steel with a leather strap is approximately £2,650 in 2026 — the least expensive way into an Hermès mechanical watch, if you're picking the mechanical reference. On the pre-owned market, a well-kept Cape Cod GM with the original double-tour strap trades at around £2,100 to £2,400. It is the Hermès watch most likely to fly under the radar and, in our view, the most under-priced piece in the collection at retail.
The Cape Cod is not currently in JULL's stock room but comes through us intermittently — email us if a Cape Cod TGM in barenia leather with a natural buckle is what you're looking for, because those disappear within days when they surface.
Arceau, Slim d'Hermès, and the mechanical watches
Beyond the three signature ladies' pieces, Hermès makes a serious mechanical watch line, most of it built around movements from the Manufacture Hermès facility in Le Noirmont, Switzerland. The Arceau — designed by Henri d'Origny in 1978 — is a round case with slightly asymmetrical wire lugs, a horseman's silhouette. It exists in leather-strap and Milanese-mesh references, and in a Petite Lune version with a moonphase that is genuinely lovely.
The Slim d'Hermès (2015, designed by Philippe Delhotal) is thinner, cleaner, and uses a Vaucher-derived movement co-developed with Parmigiani Fleurier. The Faubourg Manchette adds an integrated metal bracelet in the same slim case. Neither is currently in JULL's Knightsbridge stock, but both are pieces we source on request.
The 30-second sizing note
The single question new Hermès watch buyers ask most: which size on my wrist? A working rule from the showroom:
- If your wrist measures 13–15cm, the Kelly Watch Mini (16mm) and Heure H Mini (17.2 × 22mm) both sit correctly. The Cape Cod PM (23 × 23mm) is on the edge — try before buying. - 15–17cm wrist, the Kelly Watch Small (20mm) or Heure H Small (21 × 25mm) starts to feel proportional. Cape Cod GM (29 × 29mm) too. - 17–19cm wrist, the medium cases begin to look right. Kelly Watch Medium, Heure H Medium, Cape Cod TGM.
For evening: mini. For a working day at a desk: small. For a statement piece across a dinner table: medium. There is no rule, but this is the pattern our regulars have converged on.
Materials and the resale question
Hermès watch cases are made in stainless steel, 18k yellow gold with palladium-hardware finish, 18k rose gold, and — in older or rarer references — silver. Straps rotate through box calf, epsom, barenia, alligator (Mississippiensis and Niloticus), and — in the more recent Cape Cod references — canvas and denim.
For resale, three quiet observations from the last three years of Hermès watch traffic at JULL:
One. Diamond-pavé pieces retain value more predictably than the plain steel entry pieces, because the diamond references are not stocked deeply at boutique and buyers who want one already know what they want.
Two. Gold Heure H Minis with palladium hardware have been the fastest-moving watch category on our floor in 2025–2026. They are difficult to source at boutique and buyers are willing to pay a modest secondary-market premium.
Three. The Kelly Watch Mini in steel with a coloured epsom strap depreciates slightly more than the diamond versions, because the strap can be changed and the case is not scarce. It remains, however, one of the loveliest gifts a woman can be given, and pre-owned examples in immaculate condition sit at roughly 65–75% of new retail.

Prices are indicative retail as of Q3 2026 in London and vary by strap. Pre-owned market for the same references sits, on average, at 55–80% of new retail depending on condition, strap, and box/papers presence.
Buying pre-owned at JULL Knightsbridge
Every Hermès watch that comes through our showroom is inspected under 10× loupe magnification for case-back stamping (Hermès uses a serial-year code system similar to the bag blind stamps), tested on a quartz-accuracy timer, and — for mechanical references — sent to a Swiss-trained watchmaker before we list it. Straps are original-Hermès or replaced with new-old-stock Hermès straps only. We do not sell aftermarket-strap Hermès watches.
If a specific reference is not on our stock page, we source. Kelly Watch Small in gold with grey epsom strap, Heure H Grand automatic in barenia — both examples of pieces we have sourced through European boutiques in the last quarter. Turnaround for a sourced piece typically runs four to eight weeks and depends entirely on what surfaces in Paris.
Private viewings at Knightsbridge are by appointment only, weekdays and Saturday mornings.
Frequently asked questions
Do Hermès watches hold value?
Selectively. Diamond-pavé Kelly Watches, gold Heure H, and rarer Cape Cod references (barenia, moonphase, TGM) hold value well on the secondary market — often at 70–85% of new retail after five years. Plain-steel Kelly Watch Minis and steel Heure H Minis depreciate more predictably, sitting at 55–65% of new retail on the pre-owned market.
Is a Kelly Watch a real watch?
Yes. It uses a Swiss quartz movement, is water-resistant to 30 metres, and is serviced by Hermès. It is not a mechanical watch — but for its intended purpose (a jewellery piece with a functioning dial) the quartz movement is arguably the correct engineering choice.
Kelly Watch vs Heure H — which should I buy first?
If you have never owned an Hermès watch, the Heure H Mini in steel is the more sensible first purchase: lower entry point, more versatile with sportswear and workwear, easier to overlook. The Kelly Watch is the second Hermès watch — a jewellery-forward piece worn with intent.
Can I service my Hermès watch outside Hermès?
Quartz Hermès watches can be serviced by any qualified Swiss-trained watchmaker. For mechanical references we strongly recommend Hermès service centres or authorised retailers — the Manufacture Hermès movements require specific tooling. In London, both the Bond Street boutique and one or two independent watchmakers can handle Hermès service on quartz references.
Are Hermès watches good investments?
They are not investments in the way a Birkin 25 in a rare exotic is an investment. They are jewellery. Buy them for the object, not the exit strategy. The exceptions — Kelly Watch with full diamond pavé, gold Heure H, mechanical Cape Cod in rare straps — do accrue value, but slowly and inconsistently.
Where can I buy an Hermès watch in London?
New: the Hermès boutiques on New Bond Street and Sloane Street. Pre-owned and new-with-tags: JULL Knightsbridge (private viewing by appointment). For rare or archive references, a small handful of European auction houses and a very small handful of specialist dealers, of which we are one.
