Bersigar Ocular 1766 — Blue Dial Leather Edition
The watch
Built around a sunburst royal blue dial, the Bersigar Ocular 1766 Blue Dial Leather pairs a 40mm case with a Seiko VK64 meca-quartz chronograph movement. It brings a fixed brushed stainless steel tachymeter bezel, 100m water resistance and a sapphire crystal. It belongs to Hour V, Chronograph, in our Expedition season: a natural choice for active days that need a stopwatch on the wrist.
BERSIGAR Ocular 1766: Blue Dial Leather Edition
The BERSIGAR Ocular 1766 combines mid-century track instrumentation with a slender, ergonomic case architecture. Defined by a refined 40mm stainless steel case with an ultra-thin 11mm profile, an engraved brushed steel tachymeter bezel, a sunburst royal blue dial with bi-compax registers, bold broad-arrow hands, and a vintage tan leather strap with a deployant folding clasp, this meca-quartz chronograph delivers purposeful timing functionality with elevated vintage racing style.
Powered by the Seiko Japanese TMI VK64 meca-quartz movement, the hybrid caliber pairs quartz timekeeping accuracy with a mechanical chronograph mechanism that offers crisp tactile pusher engagement and an instantaneous zero-reset flyback hand. The sunburst blue dial features applied polished indices with strong luminous fill, a distinctive triangular 12 o'clock marker, faceted broad-arrow hands, and two sunken sub-registers tracking 60-minute elapsed timing and a 24-hour cycle. Built from solid 316L brushed and polished stainless steel, the watch is equipped with an anti-reflective sapphire crystal, classic pump pushers, a threaded screw-down crown, and 10 BAR (100M) water resistance.

From the journal
Owners say
Bought this for my husband's anniversary gift. He is picky about case sizes and prefers 40mm watches over big bulky ones. The royal blue dial and leather strap look handsome on him and he wears it to the office constantly.
Picked this up for my son when he finished flight school. The 40mm blue dial chronograph on leather has a classic pilot/racing look that fits his 7-inch wrist, and he wears it every day.
Even though it comes on calfskin leather, the 100m water resistance gives me peace of mind when I am around the marina or caught in a rainstorm. High contrast hands make it easy to read outdoors.
Thanks Gage! That 100m rating is definitely handy around the water.
The Seiko VK64 caliber is the sweet spot for affordable chronographs. You get quartz accuracy down to the second per month alongside a mechanical-feeling 5Hz chrono hand sweep and instant flyback-style reset. At 40mm in brushed 316L steel with an anti-reflective sapphire crystal, it wears slightly more compact on my wrist, just like a vintage racing timer should.
I have several Swiss automatics, yet I keep reaching for this 40mm Ocular 1766 because the proportions are spot on. The Seiko VK64 meca-quartz eliminates the ticking seconds hand, giving a clean bi-compax symmetry on the sunburst royal blue dial. The fixed brushed tachymeter bezel frames the sapphire crystal nicely, and the calfskin strap broke in quickly on my wrist.
At 40mm, this case fits my wrist without getting in the way. The brushed 316L steel case and fixed tachymeter bezel are machined cleanly, and the VK64 pushers engage with a positive click. Good everyday chronograph.
