Groomsman Gift Hit
Picked this up for my brother who served as best man at my wedding. He hasn't taken it off since the rehearsal dinner. Shipping carrier delayed the box by two days, though the watch itself arrived in great shape.
The watch
Bersigar Allegro 1673 Silver Blue: an integrated-bracelet watch in a 39mm solid 316L stainless steel case, driven by a Seiko NH35A automatic movement. It brings 100m water resistance and a sapphire crystal. We place it at Hour III (Integrated Sport) of the Boardroom season, for smart-casual offices and city weekends.
BERSIGAR Allegro 1673: Silver Blue Edition
The BERSIGAR Allegro 1673 Silver Blue embodies the pinnacle of geometric integrated-bracelet luxury sports horology. Defined by a sharp 39mm angular case, an iconic octagonal bezel secured by eight visible hexagonal screws, an integrated tapering steel bracelet, and a waffle-textured "tapisserie" gradient blue dial, this automatic timepiece delivers architectural refinement and versatile everyday luxury.
Powered by the Seiko Japanese NH35A automatic movement, the caliber provides self-winding kinetic reliability with manual winding, hacking seconds, and quickset date adjustment. The oceanic blue dial showcases a multi-dimensional micro-check waffle pattern, accented by applied polished baton indices with strong luminous fill, matching luminous hands, and a framed date window at 3 o'clock. Machined from solid 316L brushed and polished stainless steel, the watch features an anti-reflective sapphire crystal, an ergonomic folding deployant clasp, and a threaded screw-down crown delivering 10 BAR (100M) water resistance.

Owners say
Picked this up for my brother who served as best man at my wedding. He hasn't taken it off since the rehearsal dinner. Shipping carrier delayed the box by two days, though the watch itself arrived in great shape.
Wasn't sure how an online brand would compare to my Swiss pieces, but the ocean blue tapisserie dial and sapphire crystal are legit. The bracelet links were a little stiff for the first 3-4 days before breaking in nicely on my wrist.
Thanks for giving us a shot, Keith! Solid 316L integrated links can feel a bit taut fresh out of the factory wrap, so we're glad they loosened up nicely after a few days of wear.
Bought this sight unseen for casual Fridays at my law practice. The sapphire crystal and solid steel links feel much pricier than $399. My only wish is that the clasp had an extra adjustment option when my wrist swells in the August heat.
This has become my go-to watch for business casual days. The gradient blue dial pairs well with navy or grey sport coats, and the 39mm case doesn't snag on dress shirt cuffs during presentations.
I normally wear 43mm racing chronographs to track days in Indy, so I wasn't sure how a 39mm three-hander would feel on my wrist. The integrated lug profile gives it plenty of presence and the blue waffle dial looks great in sunlight.
Took two links out of the integrated 316L bracelet to fit my wrist and the taper feels balanced all day. The outer presentation box was fairly basic, though the watch is clearly where the money went.
Appreciate the review, Richard! Glad you got the integrated bracelet dialed in comfortably for your wrist.
The 39mm diameter wears closer to a 40mm due to the integrated end-links, fitting my wrist squarely. Crown action is positive, legibility against the ocean blue textured dial is clear, and the NH35A hacks and hand-winds smoothly.
Thanks for the detailed notes, Nick! You nailed it on the integrated lug geometry giving the 39mm case a slightly broader stance on the wrist. Enjoy wearing it!
I spent forty years as a machinist in New Jersey, so bad case finishing jumps right out at me. The transitions between the brushed flat surfaces and polished bevels on this 39mm octagonal case are remarkably clean for under four hundred bucks.
Ordered the blue Allegro for my husband's birthday. He is super particular about his watches and loved the octagonal bezel and textured blue dial right away. Only hiccup was the shipping carrier delayed the box by two days getting to Albuquerque.
I was hesitant ordering a $399 integrated bracelet watch online, half expecting hollow-feeling links or a tinny clasp. Once I unboxed it, the weight of the solid 316L steel and the gradient ocean blue tapisserie dial under sapphire glass won me over.
