Chrono Gunmetal Black
Cool gunmetal against two warm lenses, deliberately.
Where the Eclate colorways lean into the tint, Chrono Gunmetal Black does the opposite and sets a cool, desaturated rim against a warm lens. The contrast makes the tint look more intentional and less like a coating. Dimensions are a 49 mm eye, 20 mm bridge and 145 mm temples on a 139 mm front, with 40 mm of lens height, which is the most broadly wearable set of numbers in the whole range. If you are buying without trying the frame on first, a medium rectangle in these proportions is the low-risk choice.
Two tints, two jobs
Amber for the evening, red for the dark hours
Amber lensEvening screens and lampsThe amber tint reads 0.10% at 450 nm and 0.48% at 500 nm. Part of the green band survives, rising to 40.5% at 550 nm and 66.6% at 560 nm. It carries 100% UV protection (UV400).
Red lensIndoors, close to bedtimeBlue and green are removed entirely across 380 to 560 nm. Transmission resumes at 570 nm with 5.8%, hits 49.7% at 600 nm and 92.9% at 700 nm. Luminous transmittance is 14.9%.
All figures are single-lens spectrophotometer measurements from our own laboratory reports for this lens, tested to EN ISO 12312-1, ANSI Z80.3 and AS/NZS 1067.1. Individual response varies.
Fit
Will the Chrono fit you?
Chrono Gunmetal Black is a medium frame, 139 mm across the front, which fits the widest range of faces in this lineup. A 20 mm bridge against a 49 mm eye gives an open nose fit that rarely pinches. The 40 mm lens height is the middle of our range: enough coverage to catch a downward look, not so deep that it contacts the cheek. Temples are 145 mm. If you are unsure of your size, start here.
