A modern interpretation of IWC’s legendary aviator lineage, shaped around one of the most complete perpetual calendar displays in contemporary watchmaking.
Why we love it
This IWC Big Pilot’s Watch Perpetual Calendar IW503605 brings together the familiar presence of the Big Pilot with the quiet sophistication of IWC’s signature calendar mechanism. The watch introduces its complexity with confidence through a 46.2mm steel case, a deep blue dial, and a layout that remains readable despite the technical load it carries. The four sub-dials track the date, day, month, and moon phases for both hemispheres, all adjusted through a single crown, a hallmark of Kurt Klaus’s ingenious system. Completing the calendar complication is the year window between seven and eight.
There is a certain charm in how this watch handles information. The double moon phase at 12 adds a poetic counterweight to the power reserve display at three, while the seven-day reserve of the 52615 calibre keeps the movement running steadily through the week. Twin barrels provide the energy required for the perpetual calendar module and maintain accuracy even as the watch moves through long intervals. The brushed steel case, oversized crown and clean typeface create continuity with the broader lineage, yet the depth of the blue dial gives this version its own voice. The sapphire caseback reveals the movement and an oscillating weight bearing an 18k gold medallion, a discreet detail that elevates the finishing without changing the watch’s instrumental character.
This reference is easy to admire because it offers genuine utility without compromising the identity of the Big Pilot. It feels purposeful, mechanically sincere and visually balanced, which is why it remains one of the most compelling ways to experience IWC’s long relationship with aviation complications.
This IWC Big Pilot IW503605 has light nicks on the case and caseback. The leather strap is soiled too.
Provenance
At Second Movement, the pre-owned division of Ethos Watches, we adhere to a rigorous verification process where expert watchmakers carefully inspect every watch to certify its authenticity, ensuring it is not counterfeit. We also go to the maximum extent possible to ensure that the timepiece is not a stolen property and that all duties are paid. However, in the absence of any central database, a 100% verification is unlikely for any pre-owned entity in India. Nevertheless, we can still provide a provenance guarantee for watches purchased from Ethos.
Please note all our transactions with sellers are conducted via registered banking channels, accompanied by a signed affidavit, banking proof, and PAN card.
A specific affidavit stating the watch is not a stolen property and that all applicable duties have been paid is also obtained from the seller and is available for buyers in case of legal requirements.
We strive to build trust through transparency and diligence, outlining our verification process and the inherent limitations. Our commitment to integrity shapes every transaction, prioritising your confidence while acknowledging the realities of the pre-owned watch market.
