“Breaking through limits with an imposing arrival” — HR Factory introduces a new addition: the Omega Speedmaster Series Ref. 326.32.40.50.06.001 multifunction chronograph.
The HR team has collaborated closely with original manufacturing partners, conducting exclusive full teardown analysis and measurement mapping. With no expense spared and a full year dedicated to mold development, every structural detail and dimensional specification has been engineered to achieve full interchangeability with the original model. The watch follows the official 40mm case dimensions and adopts a Swiss-imported Cal. 3330 chronograph movement with authentic structural architecture. Through professional refinement and precision finishing, the movement delivers improved stability and durability, presenting a high-grade execution of the Speedmaster chronograph design.
The watch features a stepped case construction with CNC-level finishing and precise dimensional control. All components, including bracelet links, spring bars, and screws, are designed for full compatibility with the original specification.
The dial reproduces the original grain texture combined with radial brushing effects. The fine matte surface density closely matches the authentic model, and light reflection remains consistent under all viewing angles. Hour markers, logos, and numerals are individually molded using original-grade materials, achieving a refined three-dimensional aesthetic through multiple tooling refinements.
The crystal is a double-sided blue anti-reflective curved sapphire glass. Its chamfered edges are finely polished, and curvature tolerance is controlled to a strict 0.03 specification standard. It offers excellent scratch resistance and high clarity transparency.
The screw-down crown structure has undergone repeated testing to ensure water resistance consistent with a 100-meter rating.
The rubber strap is produced under strict material standards from the earliest stage. It provides a soft, skin-friendly wearing experience with excellent comfort. Stitching details and structural elements, including identification markings, are fully consistent with the original model.
The clasp features precise brushed finishing with consistent depth matching the original design. Both brushing density and depth have been carefully replicated. The improved structure resolves the common issue of clasp loosening over time, ensuring long-term stability and an authentic closing feel, including a faithfully reproduced clicking sound.
The movement is based on the Cal. 3330 chronograph architecture. It has been refined and optimized by a professional engineering team to enhance operational stability and improve long-term reliability, addressing traditional performance issues found in similar chronograph designs.
Strict quality control is applied throughout the entire production process. Each movement undergoes precise adjustment by watchmakers and is observed for 24 hours before leaving the factory to ensure optimal performance.
HR Factory remains committed to craftsmanship and continuous refinement, delivering high-quality timepieces for watch enthusiasts worldwide.
