The watch
Built around a sunburst yellow gold color dial, the Bersigar Luxaura 1645 Two-Tone Yellow Gold pairs a 42mm case with a Seiko NH35 automatic movement. It brings 100m water resistance and a sapphire crystal. We place it at Hour I (Minimalist Dress) of the Boardroom season, for the office and formal evenings.
BERSIGAR Luxaura 1645: Two-Tone Yellow Gold Edition
The BERSIGAR Luxaura 1645 Two-Tone Yellow Gold delivers classic horological elegance. Defined by a yellow gold color fluted bezel, a matching sunburst yellow gold color dial, and faceted baton indices, this 42mm timepiece provides a timeless, balanced aesthetic suited for formal occasions and everyday wear.
Powered by the Seiko Japanese TMI NH35 automatic movement (24 jewels), the caliber winds via natural wrist motion with no batteries required. The dial features polished baton hands, luminescent hour markers, and a date display at 3 o'clock magnified by an external cyclops lens. Built from solid 316L polished and brushed stainless steel with yellow gold color center links, it is paired with a five-link Jubilee bracelet, an anti-reflective sapphire crystal, and a threaded screw-down crown rated for 10 BAR (100M) pressure resistance.

Owners say
After thirty years of wearing black-dial pilot chronographs and GMTs, I wanted a traditional gold-dial automatic for formal dinners. The fluted bezel and baton markers are clean and easy to read.
Wears cleanly under dress shirt cuffs during hospital rounds and conferences. The sunburst gold dial and two-tone bracelet have a warm, traditional presence on my wrist.
Removed two links from the two-tone 316L bracelet for my wrist and it sits flat and balanced. Also threw it on a brown crocodile-grain leather strap for a formal dinner and the gold dial looked great.
Appreciate the review, Preston! Pairing that sunburst gold dial and fluted bezel with brown crocodile-grain leather is a classic look.
Most dressy gold-toned watches can't handle getting wet, so having 100m water resistance and a sapphire crystal on this 42mm automatic means I can wear it out at Lake Hefner on weekends without worrying.
Good 42mm fit on my wrist. Crown threads are tight at first.
Thanks for the feedback, Gabriel! Those fresh 100m crown threads and gasket can take a firm push for the first few cycles before smoothing out. Glad the 42mm case fits your wrist well!
Bought this for my older brother when he retired from the Air Force. The sunburst yellow gold dial and two-tone bracelet look classic on his wrist and he wears it to every dinner.
Picked this up for my dad's 65th birthday. He wanted a classic gold-and-steel watch with a fluted bezel, and he hasn't taken it off since his party.
When I'm not at track days wearing a tachymeter chronograph, I wear this two-tone champagne gold automatic to court. The 42mm size feels familiar on my wrist and the NH35 sweep is dead reliable.
