Big Crown Moonphase

The Oris Big Crown Moonphase brings together classic aviation heritage and the poetic complication of a moonphase, making it a standout in the brand’s pilot-inspired lineup. Originally conceived as a tribute to early 20th-century cockpit watches, this model’s signature oversized crown and clear, legible dial are more than just design flourishes—they’re rooted in genuine tool watch history. The moonphase display at six o’clock adds a layer of charm rarely found at this price point, enhancing its appeal for collectors seeking something distinct from standard date complications.

Reference variants like the Ref. 01 581 7627 4061 feature a 40mm stainless steel case, automatic movement, and sapphire crystal, with some editions offering a choice between blue, black, or silver dials. The moonphase function is driven by the reliable Oris Caliber 581, based on a modified ETA 2688/2671, known for its dependable performance and ease of servicing. Earlier and later references may differ in dial textures, applied numerals, and strap options, which can influence desirability and secondary market value.

Price variation typically tracks with dial color rarity, overall condition, and completeness of set (box, papers, original strap). Lume quality and the crispness of the moonphase disc are worth checking, as these details matter to collectors. This model doesn’t have widespread issues with aftermarket parts or counterfeiting, but original crowns and hands are preferred for long-term value. The 40mm case wears comfortably on most wrists, and with 50m water resistance, it’s practical for everyday use while retaining its vintage-inspired charm.
