MAURICE LACROIX is a Swiss watchmaker based in Zurich, known for producing in-house movements and sport-elegant designs. The PONTOS collection, introduced in 2001, features robust cases with integrated lugs, combining technical precision with contemporary styling. The PT6197 reference belongs to the PONTOS Chronograph line, which typically houses Swiss-made automatic chronograph movements such as the ML112 (based on the ETA 7750).
This is an original full watch case designed for the MAURICE LACROIX PONTOS Chronograph PT6197 prototype models. The case is crafted from stainless steel with a black ceramic PVD coating, a finish commonly used in high-end watchmaking for scratch resistance and durability. The kit includes the crystal, bezel, case-back, crown, and pushers—all components necessary for a complete case replacement or refurbishment.
The case measures approximately 38 mm in width and 43 mm in length (excluding the crown), dimensions consistent with the PONTOS Chronograph series. Condition is near-mint, with faint surface marks visible under close inspection but no signs of wear from use. This case is suitable for professional watchmakers restoring a used PT6197 or assembling a custom build using original MAURICE LACROIX parts.
Official reference: MAURICE LACROIX PONTOS Chronograph PT6197 (prototype variant). Case dimensions: 38 mm (width) × 43 mm (length, excluding crown). Lug-to-lug measurement is not specified but typically ranges between 48–50 mm for this model series. Lug width is standard 20 mm for the PONTOS Chronograph line, compatible with aftermarket and OEM straps.
Material: 316L stainless steel with black ceramic PVD (Physical Vapor Deposition) coating. The PVD process ensures a uniform, wear-resistant surface that maintains its finish longer than traditional plating methods. Crystal is likely sapphire with anti-reflective coating, a standard feature in MAURICE LACROIX cases of this era.
Included components: full case body, fixed bezel, screw-down case-back, signed crown, and dual chronograph pushers. The crown and pushers are threaded for water resistance, though the exact ATM rating for this prototype case is undocumented. No markings or engravings are present on the exterior beyond the standard MAURICE LACROIX branding on the crown.
Condition: graded Excellent in our Condition Grading Scale below. Faint surface marks are visible under direct light but do not affect structural integrity or functionality. No dents, deep scratches, or signs of prior refurbishment. The PVD coating remains intact with no flaking or peeling.
This original MAURICE LACROIX case provides a complete solution for restoring or customizing a PT6197 Chronograph, using factory-correct materials and dimensions.
The case is designed for the PT6197 prototype but shares dimensions and lug width with standard PONTOS Chronograph models. Compatibility depends on the movement and dial configuration—consult a watchmaker for verification.
The lug width is 20 mm, standard for the MAURICE LACROIX PONTOS Chronograph series. This allows compatibility with OEM and aftermarket straps of the same width.
Gaskets are not mentioned in the listing and are typically replaced during servicing. Assume new gaskets will be required to achieve factory-specified water resistance.
The crown bears the MAURICE LACROIX logo. Pushers are unsigned, consistent with the brand’s design for this reference.
Yes, but additional components (movement, dial, hands, strap) are required. The case includes all external parts except the movement and dial, making it suitable for a custom build using compatible MAURICE LACROIX or ETA-based chronograph movements.
