Chronomaster Aviator Sea Diver
Model History
The Chronomaster Aviator Sea Diver was presented by Nivada in 1963 as an instrument chronograph designed for a dual audience: pilots and divers. The name itself, combining "Aviator" and "Sea Diver," reflects the ambition to offer a single tool capable of meeting different needs, an approach typical of Nivada's output in those years, geared toward practical versatility rather than extreme specialization.
The historic pieces are recognizable by their "broad arrow" and dauphine hands, paired with a spearhead-shaped central seconds hand consistent with that of the Antarctic models of the same period. On some variants, the minute scale shows a red coloring over the first ten minutes, a feature designed for yacht racing, confirming the chronograph's multi-use vocation.
Brought back into production with the brand's relaunch, the modern Chronomaster Aviator Sea Diver is offered both in an automatic version, with a Sellita SW510 BH B movement and a bicompax chronograph function with a minute totalizer, and in a manual-winding version closer in proportions to the original 1960s pieces, both available with a wide choice of steel bracelets echoing the vintage executions.

Main Executions
The red scale over the counter's first ten minutes, found on some historic executions of the model, has no aeronautical function but a nautical one: it let regatta sailors precisely time the starting phase of sailing races, a detail that shows just how much Nivada thought of its chronographs as genuinely multi-use instruments.
