Garmin Quatix 8 AMOLED 51mm Mens Watch
Ref. 010-02905-91
Sits in Garmin’s upper tier here — more premium than three quarters of the Garmin watches we list, which start at £130.
Price range £130 to £1,499 across 71 Garmin watches in stock.The Quatix line is Garmin's dedicated marine platform, and the 51mm AMOLED sits at the top of it. Where earlier Quatix generations required a separate device to talk to the chartplotter, this one carries a built-in speaker and microphone, so voice commands reach compatible Garmin chartplotters directly from the wrist — a meaningful step when both hands are occupied and conditions are moving quickly. The marine toolset runs deep: regatta timer, tack assist, tide and anchor alerts, and the ability to control Force trolling motors, Fusion stereos and autopilots without touching the helm. At 51mm, the case is unambiguously large, and it is sized that way for a reason — in spray, glare or low light, data fields on a screen this generous are readable at a glance rather than a squint. The titanium bezel and titanium caseback sit around a fibre-reinforced polymer body, and the buttons are metal, leakproof, and designed to work with wet hands or gloves. The watch is rated for scuba and apnea diving to 40 metres, which sits comfortably inside the 100m pressure rating, and it meets military durability standards. With up to 29 days in smartwatch mode, a passage of meaningful length does not require a charging stop.

Learn more about Garmin
Gary Burrell and Min Kao founded Garmin in 1989 — the name is a contraction of their first names — to build GPS receivers for aviation and marine use. Consumer navigation came later, and wearables later still.
Unlike most names in this directory that arrived from outside watchmaking, Garmin is not a licence. It designs and builds its own devices, writes its own software and runs its own satellite-positioning stack, which is why its watches do things Swiss houses do not attempt.
The fenix line established the template in 2012: a rugged multi-sport GPS watch with mapping, altimeter and week-long battery life. Forerunner covers running, Instinct the hard-wearing end, Venu the smartwatch end, and the MARQ line puts the same electronics in titanium and sapphire at Swiss prices.
Battery life is the differentiator. Where most smartwatches are measured in days, Garmin measures in weeks, and in solar-charging models sometimes in months.
These are instruments rather than heirlooms, and they date the way electronics date — but for anyone who actually trains, they are among the few watches on the market that earn their place.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 100m it is rated for swimming and snorkelling, though not for diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedIs it a men's or women's watch?
Listed as men's.
