In-house design studio

Historical significance
Surani Mariner One Limited Edition Titanium sits within Surani's Mariner One line, introduced in 2023. It carries the house codes established since 2020 — grade 5 titanium, brushed and polished case, blue gradient sunburst with applied luminous indexes dial and sellita sw200-1 automatic, 28,800 vph, 26 jewels — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Surani works in limited editions, and the Mariner One is its signature: a 40 mm Grade 5 titanium case, a unidirectional ceramic diving bezel, a blue gradient sunburst dial and a Swiss automatic movement shown through a sapphire case back.
Jash Surani founded the house around a single idea: a Swiss-made titanium diver with real 300 m capability, made in small numbered runs rather than open production.
