Integrated Design. Sculpted Detail. Iconic Finish.
The Seikonaut Bracelet 20/16mm is more than just a companion to our Seikonaut Watch Case—it’s a carefully sculpted extension of your timepiece. With a refined integrated design and unmatched attention to detail, this bracelet completes the full sports-luxury aesthetic with both function and flair.
Crafted entirely from solid 316L stainless steel, the bracelet features a bold taper from 20mm at the lugs to 16mm at the clasp. Brushed outer links deliver a strong, tool-watch presence, while the center links steal the show.
Each center link is meticulously polished and shaped across three axes of curvature, giving the bracelet an opulent, jewel-like appearance. This complex geometry reflects light from multiple directions—creating a dynamic visual effect that adds depth, richness, and movement to your wrist.
Sized with solid screw-in links for durability and ease, and secured with a butterfly deployment clasp, this bracelet blends precision engineering with a luxury-grade finish.
While designed to pair perfectly with our Seikonaut Watch Case , this bracelet is also compatible with several of our other models—including the Explorer and GS cases.
Note: As link screws are not fully tighten for the purposes of easy resizing, ensure all link screws are tighten prior to usage.

This is the second bracelet I have purchased from Lucius Atelier and is another level in quality. It is exceptionally light and comfortable on the wrist, with a very good taper from 20 to 16mm, but visually looks more dramatic due to the svelt nature of the bracelet itself, similar to a Tissot PRX.
The clasp is exceptional, and a step above my previous experience with another LA bracelet (the Jubilee style), which I found a bit sharp and not comfortable. This clasp is smooth and even has some perlage on the underside which is just a lovely unexpected touch.
Some slight brushing on the H-links is overmatched by the polish on the midlinks. If you want something a bit less “shiny”, this may not be to your taste but I like the effect in total.
Coupled with the ultra thin explorer case, this genuinely feels like a much more expensive luxury watch. This is a complete knockout of a bracelet - bravo.
