Luxaura 1783 40mm Sunburst Blue
I had my doubts about buying a $399 watch online without seeing it in a showroom first, but the weight of the solid 316L bracelet and clarity of the sapphire crystal sold me immediately. Looks much pricier than it is.
The watch
Bersigar Luxaura 1783 Silver Blue Roman Dial: a sunburst blue-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: Silver Blue Roman Dial Edition
The BERSIGAR Luxaura 1783 Silver Blue unites classic stainless steel horology with high-utility calendar functionality. Defined by a light-catching 316L fluted bezel, a sunburst blue dial, and applied Roman numeral hour markers, this 40mm timepiece delivers a refined, executive presence suited for formal occasions and everyday wear.
Powered by the Seiko Japanese TMI NH36A automatic movement, the caliber powers an instantaneous full day-of-the-week aperture across the 12 o'clock arc alongside a date display at 3 o'clock magnified by an external cyclops lens. Machined from solid 316L polished and brushed stainless steel, the watch features an articulated President-style semi-circular three-link bracelet, a scratch-resistant sapphire crystal, and a threaded screw-down crown engineered for 10 BAR (100M) pressure resistance.

Owners say
I had my doubts about buying a $399 watch online without seeing it in a showroom first, but the weight of the solid 316L bracelet and clarity of the sapphire crystal sold me immediately. Looks much pricier than it is.
I spend weekends wrenching on vintage sports cars and weekdays on construction sites, so I wanted a clean silver-and-blue automatic for nights out. The Seiko NH36A movement is dependable and the 40mm case feels solid.
The 40mm case and fluted 316L bezel sit well on my wrist, and the Seiko NH36A movement inside is keeping +5 seconds per day. Sunburst blue dial has nice radial depth under the anti-reflective sapphire. I swapped it onto a leather strap for a few days which was pretty stiff before breaking in, and the factory bracelet clasp is a bit tight to pop open.
Ideal size for my wrist when I'm in a coat and tie at school events. The polished fluted bezel and blue Roman numeral dial look classic without being flashy, and cuff clearance is great.
Wore this to three defense-contracting briefings this week. The 40mm silver case slips under a dress shirt cuff easily on my 7.75-inch wrist, and the sunburst blue Roman dial looks sharp with navy or grey suits.
