Clean Tolerances on 42mm Case
I pay attention to typography and proportions. The Eastern Arabic numerals are balanced cleanly across the 42mm dial, end-links sit flush against the case, and the Seiko NH35 winds smoothly.
The watch
The Bersigar Luxaura Arabic Face 1645 Obsidian Black is a 42mm dress watch with an obsidian black dial, powered by a Seiko NH35 automatic movement. Expect 100m water resistance and a sapphire crystal. It belongs to Hour I, Minimalist Dress, in our Boardroom season: a natural choice for client meetings, weddings and evenings that call for a jacket.
BERSIGAR Luxaura Arabic Face 1645: Obsidian Black & Fluted Distinction
The BERSIGAR Luxaura Arabic Face 1645 unites traditional Middle Eastern typography with iconic luxury dress watch architecture. Framed by a light-catching 316L fluted bezel, a deep obsidian-black sunburst dial, and prominent Eastern Arabic numeral hour markers, this 42mm timepiece delivers an authoritative, culturally rich presence tailored for black-tie gatherings, boardroom meetings, and refined everyday wear.
At the heart of the watch beats the renowned Seiko Japanese TMI NH35 automatic movement, a workhorse self-winding caliber celebrated worldwide for its exceptional precision, hacking seconds, and battery-free reliability powered by the natural motion of your wrist. The dial features a brilliant crystal marker at 12 o'clock, polished hands, and a dedicated 3 o'clock date window with a cyclops magnification lens for effortless readability. Forged from solid 316L polished and brushed stainless steel, it is fitted with a classic five-link Jubilee-style bracelet, an anti-reflective and fingerprint-resistant sapphire crystal, and a threaded screw-down crown rated for 10 BAR (100M) pressure resistance.

Owners say
I pay attention to typography and proportions. The Eastern Arabic numerals are balanced cleanly across the 42mm dial, end-links sit flush against the case, and the Seiko NH35 winds smoothly.
Wasn't sure what to expect at $310, especially with a fluted bezel where cheap finishes look plastic. Once I opened the box I was impressed by the weight of the solid 316L links and the deep gloss of the black dial.
Thanks for giving us a shot, Jose! Glad the solid 316L steel and obsidian black dial made a great impression.
Straightforward spec sheet: 42mm polished and brushed 316L steel, 100m water resistance, sapphire crystal, and a hacking Seiko NH35 caliber. Clasp locks firmly and the Eastern Arabic numerals are cleanly applied.
Eastern Arabic numeral dials are tough to find under $500 with a real mechanical movement, so I grabbed this 1645 right away. The applied indices have crisp edges against the obsidian black dial, and the anti-reflective sapphire crystal keeps reflections down. Even on my wrist the 42mm case wears comfortably thanks to the curved lugs, and the Seiko NH35 is running +4 sec/day.
42mm 316L steel case, fluted bezel, anti-reflective sapphire crystal, and a Seiko NH35 automatic movement. Daylight legibility on the black Arabic dial is crisp. Lume is decent for a few hours at night, though not an all-night torch.
Gave this to my best man before my wedding and he couldn't stop staring at the Eastern Arabic numerals against the black dial. Only hiccup was that bracelet resizing took us 15-20 minutes with stubborn pins.
I usually collect aviation chronographs, so this 42mm fluted-bezel piece with Eastern Arabic numerals adds something distinct to my watch box. The Seiko NH35 automatic keeps steady time, though the crown action was a little stiff out of the box before working it a few times.
Picked this up for my brother's 60th birthday after he admired an Eastern Arabic dial watch on a trip to Dubai. He loves the 42mm presence and black dial, though he noted the clasp could use an extra micro-adjustment hole for hot afternoons.
Sharp Eastern Arabic numerals on the black dial. Has some real heft that took two days to get used to.
Thanks for the review, Stephen! That 42mm solid steel case definitely has a solid feel on the wrist.
Sized the steel bracelet for my wrist, and also picked up a matte black leather strap which gives the obsidian black Eastern Arabic dial a dressier look. Rotor has a slight audible whir in a dead-quiet room.
