Oris TT1 Engine Date

The TT1 Engine Date is a new addition to the TT1 line that celebrates the connection Oris has enjoyed with motor sport for half a century. Echoing the lines of a Formula 1 car, the new watch model is a statement piece, defined by its dramatic architecture.

The TT1 Engine Date’s 42mm stainless steel case is hunched and angular; the multi-layered dial is part skeletonised to reveal glimpses of the inner workings of the watch’s mechanical movement; and the crown and dial ring are grooved and fluted to reflect the precision, detail and finesse of motor sport engineering.

Oris’s designers have refined the design of the new TT1. Its case has been streamlined to sit more elegantly on the wrist, while the signature muscular lugs have been shortened so that both the pivoting stainless steel bracelet and black rubber strap fit more ergonomically around wrists of varying sizes.

The dial is even more three-dimensional than in previous models, with a skeletonised date disc, faceted applied numerals and the fluted dial ring. The case and bracelet’s combination of brushed and polished elements complete the watch’s athletic form.

Inside the new TT1 is a mechanical movement based on Sellita SW 200-1 calibre that powers the timekeeping functions with sweeping seconds hand and a date indication at 6 o’clock.

The movement’s bridges have a smokey, anthracite finish that adds to the watch’s brooding, masculine feel and textured aesthetic.

Both the seconds hand and the date indicator are coloured in Williams blue to signify the relationship between the two companies.
