40mm 100m VK63 Chronograph
Most chronographs can barely handle a splash of rain, so having 100m water resistance and a solid steel bracelet on this 40mm piece is a huge plus for lake weekends.
The watch
The Bersigar Luxaura 1644 Black Dial is a 40mm chronograph with an obsidian black dial, powered by a Seiko VK63 meca-quartz hybrid movement. Highlights include a fixed 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 active days that need a stopwatch on the wrist.
BERSIGAR Luxaura Chronograph: Black Dial Edition
The BERSIGAR Luxaura Chronograph Black channels pure racing DNA through a stealthy, high-precision aesthetic. Defined by a fixed black tachymeter bezel, an obsidian black dial featuring concentric silver sub-register rings, and an all-stainless steel construction, this 40mm motorsport chronograph delivers exceptional legibility and timeless sports elegance suited for active track use and daily formal wear.
Powered by the Seiko Japanese VK63 Meca-Quartz hybrid caliber, the movement unites the dependable accuracy of quartz regulation with the crisp mechanical feel and instant zero-reset of a traditional chronograph. The tri-compax layout features sub-dials tracking 60-minute elapsed intervals, running seconds, and a 24-hour cycle, balanced by applied luminescent indices, polished hands, and an angled date display at 4:30. Machined from solid 316L polished and brushed stainless steel, the watch is fitted with a matching three-link Oyster-style bracelet, a scratch-resistant sapphire crystal, screw-down pushers, and a threaded crown engineered for 10 BAR (100M) pressure resistance.

Most chronographs can barely handle a splash of rain, so having 100m water resistance and a solid steel bracelet on this 40mm piece is a huge plus for lake weekends.
Took two links out to fit my wrist and the bracelet balances the 40mm head nicely. Also tried it on a grey NATO strap for weekend yard work and it looks like a proper track timer.
Gave this to my husband for our anniversary. He is super picky about watches and loved the black dial and silver subdial rings immediately. The outer presentation box was fairly basic, though the watch is where the money went.
Happy anniversary, Laura! We're so glad your husband loves the watch, and we appreciate your feedback on the outer box.
Wore it on the factory 316L bracelet for a week on my 7.5-inch wrist, then swapped it onto a black perforated rally leather strap. The silver-ringed subdials and tachymeter bezel look awesome on both.
For $240 I wasn't sure if the bracelet or bezel would feel cheap, but the solid 316L steel links and sapphire crystal really impressed me when it arrived. Sits nicely on my wrist.
I take my vintage Mustang to weekend car meets and wanted a classic black-and-silver tachymeter chronograph. The VK63 pushers have a firm mechanical click and the sub-registers are super easy to read.
At 40mm across, this Luxaura 1644 wears like a vintage 1960s motorsport chronograph on my wrist. The silver-ringed sub-registers pop against the obsidian black dial, the fixed tachymeter bezel is cleanly engraved, and the flat sapphire crystal has effective anti-reflective coating. The Seiko VK63 hybrid movement gives a crisp mechanical pusher click and instant snap reset.
Thank you for the detailed review, Alan! Those 40mm proportions and silver-ringed sub-registers were designed right around that classic motorsport chronograph look. Enjoy wearing it!
Bought this for my husband's birthday. I loved the clean silver rings on the black dial, and he hasn't stopped talking about how smoothly the stopwatch hand resets.
At 40mm this chronograph is compact enough to clear my shirt cuffs during meetings while still looking sporty after hours. The black dial with silver subdial rings is clean and legible.
The 40mm case proportions on the Luxaura 1644 are spot on for my wrist. Having the Seiko VK63 meca-quartz hybrid inside means you get a thin profile, quartz reliability, and a mechanical 1/5-second sweep with instant zero reset. The silver-ringed sub-registers against the obsidian black dial and fixed tachymeter bezel give it a classic racing look under the AR sapphire crystal.
