The watch
Built around a sunburst emerald green dial, the Bersigar Ocular 1766 Emerald Green Leather pairs a 40mm case with a Seiko VK64 meca-quartz chronograph movement. Expect a fixed brushed stainless steel tachymeter bezel, 100m water resistance and a sapphire crystal. On the ChronoSeasons dial it sits at Hour V — Chronograph, part of the Expedition season — and suits driving days, flights and timing anything that matters.
BERSIGAR Ocular 1766: Emerald Green Leather Edition
The BERSIGAR Ocular 1766 Emerald Green Edition combines vintage track instrumentation with an ultra-slender, ergonomic case architecture. Defined by a refined 40mm stainless steel case with a slim 11mm profile, an engraved brushed steel tachymeter bezel, a sunburst emerald green dial with bi-compax registers, bold broad-arrow hands, and a vintage olive-green leather strap fitted with a comfort folding clasp, this meca-quartz chronograph delivers purposeful timing functionality with elevated mid-century 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 green 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.

Bought this for my dad's retirement party since green is his favorite color. He put it on right at the table and kept showing off the sunburst dial to everyone.
With a smaller wrist, 42mm chronographs often overhang my lugs, so this 40mm Ocular 1766 is a welcome fit. The Seiko VK64 meca-quartz movement delivers a crisp mechanical reset and smooth chrono sweep while keeping quartz accuracy. Brushing on the 316L case and fixed tachymeter bezel is uniform, and the sapphire crystal has effective AR coating over the sunburst emerald dial.
Great looking green watch for work and casual dinners, and the leather is comfortable on my 7-inch wrist. Only minor complaint is the subdial numerals are a little small without my reading glasses.
Thanks for the review, Harrison! Bi-compax subdials on a 40mm dial definitely pack the numbers in closely, glad you're enjoying the emerald green finish.
Took this on a coastal weekend trip in Carolina. Having 100m water resistance on a 40mm chronograph means I don't have to take it off around the dock, and the dial is very legible.
Deep emerald green color in the sun. Light and comfortable on the wrist.
The emerald green dial paired with the fixed brushed tachymeter bezel reminds me of vintage British racing timers. The Seiko VK64 pushers click cleanly and the dual sub-registers are easy to read when driving.
Love that British racing green comparison, Julian! Thanks for sharing your thoughts.
Wasn't sure if a $205 green dial watch would look cheap in person, but the sunburst emerald finish and anti-reflective sapphire crystal are genuinely impressive. The brushed 316L steel case and tachymeter bezel feel solid on my wrist.
The stock leather strap is comfortable, but this emerald green dial really comes alive when you swap on a tan suede or two-piece khaki NATO strap. Standard lugs make swapping straps a breeze.
The emerald green sunburst dial on calfskin leather looks refined with a sport coat or dress shirt at the office. At 40mm it sits neatly under my cuff and feels light on my wrist.
