Explorer Bear Grylls spotted wearing a Bremont

Bear Grylls has never been a watch collector who poses for wrist shots in hotel lobbies. The former SAS soldier and endurance expert is spotted most authentically in contexts where gear fails or survives — and the Bremont ALT1-P on his wrist is precisely the kind of instrument that earns its keep in those environments.

The ALT1-P is Bremont's foundational pilot's watch, a reference that crystallises everything the British brand set out to prove when Nick and Giles English founded the company in 2002. The case measures 43mm and is constructed using Bremont's patented Trip-Tick system: three interlocking sections of hardened aerospace-grade steel with a distinctive knurled central barrel that rotates independently. It is rated to 100 metres of water resistance and passes a suite of MIL-SPEC tests covering shock, vibration, temperature extremes, and electromagnetic interference — tests that most luxury sports watches never face.

The movement inside is a heavily modified ETA 2824-2, regulated and cased in-house by Bremont to a standard the brand designates BE-36AE. Bremont adds anti-magnetic shielding and tunes the movement to chronometer-level tolerances. A signature feature of the ALT1-P is the GO/NO-GO crown indicator — a red and green visual cue confirming whether the crown is fully seated and the case sealed. Small detail, serious purpose.

For collectors, the ALT1-P occupies an honest middle ground: not a dress watch, not a dive watch stretched to cover aviation aesthetics, but a purpose-built instrument with a verifiable engineering brief. Bremont's early reputation was built substantially on this reference and its close variant, the ALT1-Z, which carries an additional alarm complication. The ALT1-P remains the cleaner, more wearable expression of that philosophy.

Grylls is a natural ambassador for the marque — he has worked formally with Bremont in the past — but his continued use of the ALT1-P in field settings carries its own endorsement weight beyond any contract. Retail pricing sits around $3,495, with grey-market examples trading closely to list given steady demand and Bremont's controlled production.
