Best outdoor smartwatch under £600
Launched near £900 and now about £548 — the same titanium, sapphire and AMOLED screen for a third less, because a newer model exists.
Garmin epix Pro (Gen 2) Sapphire, 51 mm
Garmin
Why this one
Nothing near this price comes close on materials: a titanium bezel, a real sapphire crystal and a 1.4-inch AMOLED screen, on a watch that still runs about a month between charges. It came down from roughly £900 for one reason — Garmin released a successor — and that has not made the watch any worse. Full offline maps, multi-band GPS and the built-in torch are all still here. The honest drawback is the size: at 51 mm this is the largest case Garmin makes, and on a slim wrist it looks and feels like exactly that. Try the 47 mm if you are unsure. Stock is also nearly gone — outgoing models do not get restocked. See the panel below for the count when this was last checked.
Before you buy
Will it fit?
- Case width
- 51 mm
- Lug-to-lug
- 51 mm (integrated)
- Thickness
- 14.9 mm
The largest case Garmin makes. Suited to about 18 cm (7 in) and above; on anything smaller it is a deliberate statement rather than a watch.
Lug-to-lug is the measurement that decides fit, and the one most makers leave off the spec sheet. Check it against your wrist →

Buy
Down from roughly £900 at launch because a successor shipped. When this was last checked there were two units left, down from three a few hours earlier. Outgoing models are not restocked, so this one does not get cheaper — it disappears.

Who you are buying from
Ashford Retail Ltd
A marketplace seller, not Amazon and not Garmin. Amazon's 30-day return window still covers you if it arrives wrong, but Garmin's warranty is honoured through authorised dealers — assume you may have to argue for it. On a discontinued model at a third off, that is the trade.
Seller of record on 6 September 2026. Amazon listings change hands — check the “Sold by” line on the product page before you pay.
What it beat
- 02 Garmin fenix 8The newer answer, and roughly double the price for gains most people will not use.
- 03 Garmin epix Pro 47 mmThe same watch in a size that suits more wrists — take this one if 51 mm is too much.
- 04 Apple Watch Ultra 2Better as an everyday smartwatch, hopeless on a trip longer than two days.
- 05 Coros Vertix 2Excellent battery, weaker mapping and a less finished interface.
