Launched in 2009, the Marin 1 features Speake-Marin's first in-house movement, a grade 5 titanium case, flame-blued hands, two-piece oven-fired enamel dial and stainless steel Piccadilly case.
Its three concentric rings for the minutes were inspired by early pocket watch chronographs.

Marin 1 Mk I was the first Speake-Marin model to feature the SM2 calibre, an in-house calibre, designed and manufactured by Speake-Marin.
It took three years to develop.

 
The SM2 Calibre has been described as a “watchmaker’s movement”
The balance wheel is large (weight of balance is 0118gr inertia 25 mg.cm2) and oscillates at 21,600 vph.
The plates and bridges are made in untreated German silver.
All bridges, levers and the mainplate are finished by hand (circling, spotting and polished).
The rotor wheel angles are hand-finished then the surface is mirror-finished.
All pivots are burnished.
The SM2 has a power reserve of 72 hours, features 29 jewels and contains 211 components altogether.
