The watch
Bersigar Luxaura 1783 Slate Grey Green Roman Dial: a sunburst slate grey-dial dress watch in a 40mm case, driven by a Seiko NH36A automatic movement. It brings 100m water resistance and a sapphire crystal. It belongs to Hour I, Minimalist Dress, in our Boardroom season: a natural choice for days that start in a meeting room and end at dinner.
BERSIGAR Luxaura 1783: Slate Grey Green Roman Dial Edition
The BERSIGAR Luxaura 1783 Slate Grey pairs executive sports styling with distinguished classical elements. Defined by a precision-machined 316L fluted bezel, a sunburst slate-grey dial featuring forest-green Roman numerals, and a solid President-style bracelet, this 40mm timepiece delivers a commanding wrist presence suitable for formal engagements and everyday wear.
Powered by the Seiko Japanese TMI NH36A automatic movement, the caliber operates an instantaneous full day-of-the-week aperture across the 12 o'clock arc alongside a cyclops-magnified date window at 3 o'clock. Machined from solid 316L polished and brushed stainless steel, the watch is fitted with an articulated President-style semi-circular three-link bracelet, an ultra-hard sapphire crystal, and a threaded screw-down crown providing 10 BAR (100M) pressure resistance.

From the journal
Owners say
Most of my weekend watches are pilot chronographs, so I wanted a clean automatic for regional flights and board meetings. The Seiko NH36A day-date sets quickly after landing and the 40mm case feels solid on my wrist.
Wore it on the factory 316L steel bracelet for a week after taking out two links for my 7-inch wrist, then tried it on a dark green Saffiano leather strap. That green strap pulls out the green Roman numerals nicely.
I've always liked the slate grey and green Roman numeral dial layout, and this 40mm execution hits the right notes. The radial sunburst brushing on the grey dial shifts nicely in sunlight, and the green print on the numerals is sharp with zero bleed under a loupe. Inside, the Seiko NH36A automatic hacks and winds smoothly, holding +4 seconds a day on my wrist.
Thanks for the detailed review, Brian! Glad the dial printing and NH36A accuracy stood up to the loupe test.
Wears comfortably through long days at the cardiology clinic and looks polished under a white coat or suit jacket. The 40mm case sits flat on my wrist and the slate grey sunburst dial is understated.
Bought this slate grey and green Roman dial watch for my dad's 60th birthday since he's a huge tennis fan. He recognized the Wimbledon-inspired colorway right away and has been wearing it to the office all week.
Checked the specs out of the box: 40mm 316L steel case, polished fluted bezel, AR sapphire crystal, and a Seiko NH36A automatic movement. High contrast between the green Roman numerals and slate grey dial makes reading the time easy.
The sunburst slate grey dial with green-outlined Roman numerals looks super sharp with charcoal and navy suits in client architecture reviews. At 40mm it clears my dress shirt cuffs cleanly on my wrist.
