Unworn Blancpain L-Evolution Semainier Grande Date, Stainless Steel, 43.5mm, Ref# 8837‑1134‑53B, box and papers

The Blancpain L‑Evolution Semainier Grande Date 8 Jours, Ref# 8837‑1134‑53B is a bold fusion of modern design and haute horlogerie, one of Blancpain's most impressive technical achievements. Housed in a 43.5 mm polished stainless steel case with subtly sandblasted recessed lug sides, this unworn piece sports a multi-layered skeletonized Grey dial, revealing a fine Côtes de Genève finish on the mainplate beneath its polished, lume-filled hands and applied hour markers. The dial combines structure and transparency, with a printed minute track adding clarity to the visual depth. Functionally powerful, the watch offers: a large double-window date at 6 o’clock; a day-of-the-week subdial at 12, featuring an 8‑day power‑reserve hand; a week indicators around the dial’s perimeter. These calendar features are adjusted easily using discrete corrector buttons hidden beneath the lugs—no tools required, preserving the case’s clean lines. Under the sapphire caseback resides the Blancpain Calibre 37R8G, a self-winding movement with 46 jewels, beating at 28,800 vph and a phenomenal 192-hour (8-day) power reserve, powered by three mainspring barrels. Secured to the wrist with an unworn matte black alligator strap and deployant buckle, featuring 100m water resistance and a scratch-resistant sapphire crystal, this model embodies both luxury and durability — a contemporary statement in Blancpain’s legacy of fine Swiss watchmaking.
