IWC Schaffhausen unveiled a groundbreaking timepiece that redefines the boundaries of mechanical watchmaking: the Big Pilot’s Watch Shock Absorber Tourbillon Skeleton XPL (Ref. IW357701). This extraordinary wristwatch is not just another entry in IWC’s legendary Big Pilot’s lineup; it’s a statement of engineering dominance, bold innovation, and the brand’s fearless push into the future of resilient haute horlogerie.
This timepiece marks a historic first for IWC: it features the integration of the patented SPRIN-g PROTECT® shock absorber system into a tourbillon-equipped movement. This breakthrough elevates the durability of a traditionally delicate mechanism—the tourbillon—to unprecedented heights. For watch aficionados, engineers, collectors, and adventurers alike, this is more than a luxury accessory; it’s a mechanical marvel sculpted for extreme resilience.
Designed and developed by IWC’s experimental engineering division, XPL (eXtended Performance Laboratory), this model embodies the essence of cutting-edge horological science. XPL’s mandate is clear: reimagine mechanical watchmaking for environments previously considered inhospitable to traditional timepieces. With the new Skeleton XPL, IWC presents a watch that thrives in high-impact, high-stress environments while maintaining the aesthetic and technical sophistication collectors demand.
With the Big Pilot’s Watch Shock Absorber Tourbillon Skeleton XPL, IWC has done what few thought possible: protect the tourbillon with a shock absorber system capable of withstanding over 10,000 g of force.
This is accomplished through the newly adapted SPRIN-g PROTECT® system. At its core lies a re-engineered cantilever spring crafted from Bulk Metallic Glass (BMG)—a material with properties unlike any traditional metal. Thanks to its amorphous microstructure, BMG possesses extraordinary elasticity and energy dispersion capabilities, making it the ideal material to defend one of watchmaking’s most intricate mechanisms against brutal shocks.
Adapting this system to accommodate the IWC-manufactured 82915 calibre with its flying tourbillon was no small feat. The cantilever spring had to be re-imagined entirely. Eight redesigned arms distribute energy evenly, reducing peak acceleration loads that could otherwise destroy the finely tuned movement.
And rigorous testing proved its value: the movement continued to function after enduring simulated shocks exceeding 10,000 g—an almost unimaginable figure in the world of watchmaking.
The plates, bridges, and rotor of the 82915 calibre are expertly skeletonised to achieve the optimal balance of weight reduction and structural integrity. Even the triangular hour and minute hands, generously coated with Super-LumiNova®, are open-worked.
This design approach does more than aid the watch’s shock resilience—it also creates a stunning, transparent display of mechanical art. At 6 o’clock, the 56-part, 0.663-gram flying tourbillon cage floats like a celestial body in orbit, a constant visual reminder of the precision and fragility now made robust through IWC’s genius.
The result is a formidable 80-hour power reserve, allowing the wearer to set the watch down for days without worrying about its precision. It’s a blend of robust engineering and enduring performance that complements the watch’s central mission: ultimate resilience.
The result is a 44.0 mm case that feels feather-light on the wrist yet can survive the roughest conditions. The material is hypoallergenic, corrosion-resistant, and virtually indestructible in daily wear. The black dial, minimalist and sleek, maintains classic Big Pilot aesthetics with its triangle marker at 12 o’clock and high-contrast minute scale.
Flanking the case are rubber bumpers—a nod to the technical and protective nature of the watch, emphasizing its readiness for high-intensity use.
Securing the watch is a Ceratanium® pin buckle, maintaining aesthetic consistency and material integrity throughout the entire build.
Thanks to the lightweight Ceratanium® and ergonomic case profile, it wears comfortably on a wide variety of wrist sizes. Whether in a cockpit, climbing expedition, or boardroom, the Skeleton XPL asserts authority without excess bulk.

The Legacy of Innovation at IWC Schaffhausen
IWC has long been revered for its fusion of engineering precision and elegant design. Founded in 1868 in Schaffhausen, the brand has continuously pushed the envelope in crafting watches that combine functional innovation with timeless aesthetics. The launch of the Big Pilot’s Watch Shock Absorber Tourbillon Skeleton XPL represents another milestone in this ongoing journey.Designed and developed by IWC’s experimental engineering division, XPL (eXtended Performance Laboratory), this model embodies the essence of cutting-edge horological science. XPL’s mandate is clear: reimagine mechanical watchmaking for environments previously considered inhospitable to traditional timepieces. With the new Skeleton XPL, IWC presents a watch that thrives in high-impact, high-stress environments while maintaining the aesthetic and technical sophistication collectors demand.
The Marvel of the Tourbillon: Protected at Last
At the heart of this watch is the flying minute tourbillon, a horological complication revered for its elegance and mechanical ingenuity. Originally invented in the 18th century to counteract the effects of gravity on a watch’s escapement, the tourbillon remains a hallmark of fine watchmaking. Yet its delicacy has always made it vulnerable to impact and vibration.With the Big Pilot’s Watch Shock Absorber Tourbillon Skeleton XPL, IWC has done what few thought possible: protect the tourbillon with a shock absorber system capable of withstanding over 10,000 g of force.
This is accomplished through the newly adapted SPRIN-g PROTECT® system. At its core lies a re-engineered cantilever spring crafted from Bulk Metallic Glass (BMG)—a material with properties unlike any traditional metal. Thanks to its amorphous microstructure, BMG possesses extraordinary elasticity and energy dispersion capabilities, making it the ideal material to defend one of watchmaking’s most intricate mechanisms against brutal shocks.
SPRIN-g PROTECT®: Engineering Brilliance in Motion
IWC’s SPRIN-g PROTECT® shock absorber isn’t just a clever add-on; it’s a meticulously engineered system. It acts like a suspension cradle, allowing the movement to float independently within the case when subjected to sudden impacts. The coupling system between the crown and the movement can disengage, allowing the entire movement to shift and compress the spring system rather than absorb the full shock directly.Adapting this system to accommodate the IWC-manufactured 82915 calibre with its flying tourbillon was no small feat. The cantilever spring had to be re-imagined entirely. Eight redesigned arms distribute energy evenly, reducing peak acceleration loads that could otherwise destroy the finely tuned movement.
And rigorous testing proved its value: the movement continued to function after enduring simulated shocks exceeding 10,000 g—an almost unimaginable figure in the world of watchmaking.
Skeletonisation for Performance and Beauty
One of the most visually arresting aspects of this watch is its skeletonised movement. More than just a stylistic decision, skeletonisation serves a critical functional purpose: it reduces the overall mass that the shock absorber must protect. The less mass, the less energy to dissipate during an impact.The plates, bridges, and rotor of the 82915 calibre are expertly skeletonised to achieve the optimal balance of weight reduction and structural integrity. Even the triangular hour and minute hands, generously coated with Super-LumiNova®, are open-worked.
This design approach does more than aid the watch’s shock resilience—it also creates a stunning, transparent display of mechanical art. At 6 o’clock, the 56-part, 0.663-gram flying tourbillon cage floats like a celestial body in orbit, a constant visual reminder of the precision and fragility now made robust through IWC’s genius.
Power and Practicality: The IWC Calibre 82915
Powering the Skeleton XPL is the IWC-manufactured calibre 82915, an automatic movement that combines technical efficiency with luxurious refinement. It features the brand’s Pellaton winding system, which utilizes movements of the rotor in both directions to rapidly build up energy in the barrel. The winding system is enhanced with ceramic components for superior longevity and reduced wear.The result is a formidable 80-hour power reserve, allowing the wearer to set the watch down for days without worrying about its precision. It’s a blend of robust engineering and enduring performance that complements the watch’s central mission: ultimate resilience.
Ceratanium®: A Case as Bold as the Movement Inside
No discussion of the Big Pilot’s Watch Shock Absorber Tourbillon Skeleton XPL would be complete without paying homage to its case—crafted entirely from Ceratanium®, an IWC-exclusive material introduced in 2017. Ceratanium® begins life as a proprietary titanium alloy, which is then milled, finished, and kiln-fired. During the firing process, the surface undergoes a ceramization transformation, acquiring the hardness, scratch-resistance, and dark matte finish of ceramic while retaining the toughness and lightweight properties of titanium.Flanking the case are rubber bumpers—a nod to the technical and protective nature of the watch, emphasizing its readiness for high-intensity use.
Black Rubber Strap with Calfskin Inlay
Completing the ensemble is a black patterned rubber strap, which integrates seamlessly with the rugged yet refined case design. The strap includes a black calfskin inlay, giving it a luxurious feel while ensuring all-day comfort and durability.Securing the watch is a Ceratanium® pin buckle, maintaining aesthetic consistency and material integrity throughout the entire build.
