COIBA Built to Keep Moving The BOCA Coiba marks a new chapter in our watch collection — a mechanical timepiece with a strong vintage character, designed around the beauty of an automatic movement. Its design takes inspiration from classic exploration and instrument watches, combining a distinctive stainless steel case with bold, highly legible dials and carefully considered details. The oversized crown and rotating bezel give Coiba a purposeful character, while the sapphire-coated crystal adds enhanced resistance to everyday wear while preserving the vintage character of the watch. Available in three distinctive dial colors — Ivory, Black, and White — each version gives Coiba its own personality. The Ivory and Black dials feature vintage-style Arabic numerals with warm luminous tones and subtle red accents, creating a distinctly retro character. The White dial takes a cleaner approach, with luminous circular hour markers and striking blue hands that give the watch a fresher, more contemporary expression. Despite their differences, all three share the same balanced minute track and strong visual identity. At its heart is the Japanese Miyota 8210 automatic movement , a mechanical movement powered by the motion of the wrist. With 21 jewels and an approximate 42-hour power reserve , Coiba requires no battery — a reminder of the mechanical tradition that has defined watchmaking for generations. Like every BOCA watch, Coiba is paired with one of our signature handcrafted leather straps, made in Mexico by our artisans . Each strap is carefully woven by hand, bringing texture, warmth, and individuality to the watch. Natural variations in the leather and handwork ensure that no two straps are exactly alike. The contrast between the mechanical movement, tool-watch-inspired case and handcrafted leather creates a watch that feels rugged yet refined — a meeting point between precision and imperfection, function and character. Designed in the spirit of BOCA's philosophy — Italian Design × Mexican Craft — Coiba is made for those who appreciate the ritual of wearing a mechanical watch and the character it develops over time.
