The PX‑02 is a limited release capped at 99 individually marked units worldwide. We allocate each piece strictly following the sequence of completed payment.
All newly confirmed pre‑orders will be shipped in May 2027. We do not rush assembly for faster delivery. Every component is fitted, adjusted and tested manually to meet our internal benchmark.
Delivery Terms Reminder This order is shipped under DAP terms. All import duties, local tax and customs clearance charges at your receiving country fall to the buyer. We suggest you check your local customs rules before checkout. Thank you for standing with ROARING CALF on this slow, focused watchmaking journey.

Racing Logic Built Into The PX‑02
On a race track, raw speed is easy to chase. Sustained stability under long‑duration load is far harder. This is the core thought we carried into the PX‑02 project.
Many shortcuts could shorten lead time, but we chose to reject them. Custom part fabrication, iterative fitting, extended running‑in and repeated timing checks are all non‑negotiable steps for us.
Drawing inspiration from race machinery architecture, the PX‑02 combines sharp structural lines and restrained industrial aesthetics. Its open‑worked movement lets you observe the tourbillon’s steady motion, paired with a precision‑machined Grade 5 titanium case that balances light weight and solid rigidity.
Low finishing yield and hand‑dependent assembly limit how many we can build. That is why this edition stays small.
LET THE WORLD HEAR YOUR ROAR
Free‑Sprung Tourbillon Movement
The beating heart of PX‑02 adopts a free‑sprung tourbillon layout. Compared with traditional tourbillon structures, this design delivers more consistent timekeeping performance across different positions.
Each bridge and gear set receives hand‑worked edge finishing and surface decoration. The open framework keeps the mechanism visible, turning steady mechanical rotation into a visual feature, just like exposed racing engine parts. Every finished movement will go through continuous running tests before final sign‑off.
Grade 5 Titanium Case Construction
We picked Grade 5 titanium for its balanced strength, low density and excellent anti‑corrosion property. Excess material is removed via high‑precision CNC machining, so we cut weight without weakening the shell structure. A mixed finish of brushing and micro‑blasting reduces fingerprint marks and delivers a subdued, mechanical texture.
Anti‑Reflective Sapphire Crystal
Double‑sided anti‑reflection coated sapphire protects the dial and internal movement. High light transmittance reduces glare under varied lighting conditions, so you can view the skeleton mechanism clearly in most scenarios.
Screw‑Down Crown & Sealing System
The ergonomic screw‑down crown is shaped for smooth adjustment. Integrated sealing structure preserves the watch’s daily water resistance. The ROARING CALF logo is finely engraved on the crown top surface.
On‑Wrist Character
We tuned the overall weight and case geometry with long‑time wearing in mind. The slim titanium case sits naturally on the wrist, fitting both casual daily wear and private collector occasions.
The open‑work dial creates layered visual depth without bulky visual weight. From different viewing angles, you discover new details of the race‑inspired mechanical architecture.
Warranty & After‑Sales Support
This ROARING CALF PX‑02 comes with a 3‑year international warranty, valid starting from the shipment date.
The warranty covers manufacturing defects of movement and case assembly. It does not cover damage caused by impact, surface scratches, unauthorised disassembly or improper use.
