HAMILTON Chronograph Lemania 1873 Reference 2630 Watch Case

Overview

This is an original, Swiss made watch case for the Hamilton chronograph designed for the Lemania 1873 movement. The case is a complete assembly, crafted from polished stainless steel and featuring a fixed bezel with a distinctive integrated gold-colored ring. It is supplied in its original, unused condition, graded Excellent in our Condition Grading Scale below.

The assembly includes the bezel, the front and back crystals, the two chronograph pushers, and the screw-down case-back. A crown and stem are not included. This is a genuine Hamilton component, marked accordingly on the case-back, and was produced for the specific reference that housed the manually wound Lemania 1873 chronograph caliber.

Hamilton, an American brand with a long history of Swiss manufacturing, utilized this robust case design for its chronographs during the era of the Lemania 1873. The case is offered as a complete unit for collectors, restorers, or watchmakers seeking an authentic, new-old-stock replacement or a foundation for a dedicated build project.

Specifications

The case has a diameter of approximately 36 mm. It is made from solid, polished stainless steel. The fixed bezel incorporates an integrated gold-colored ring. The assembly includes the bezel, the mineral or acrylic crystals, the two chronograph pushers, and the screw-down case-back. The crown is not part of this offering.

The solid steel case-back is screw-down type and is marked HAMILTON Watch Co. | Lancaster, Pennsylvania | USA | 2630. The reference number 2630 corresponds to the specific case model engineered for this chronograph.

Compatibility

This case is designed specifically for Hamilton chronograph watches built around the Lemania 1873 movement. It will accommodate the Lemania 1873 chronograph movement, also known as the Omega 861, along with its associated dial and handset. Correct fitting requires a compatible crown and stem specific to the Lemania 1873 movement. The case is intended for professional installation by a watchmaker.

  • The article is sold β€œAS IS”. Please read our Warranty Policy before purchasing.
  • Any parts not explicitly mentioned in this description or not visible in the accompanying photographs are not included.
  • Colors may appear slightly different across various screens and devices so we cannot guarantee an exact screen–to–reality color match.

This Hamilton Reference 2630 case provides a genuine, unused foundation for restoring a classic Lemania 1873 chronograph or for a dedicated custom project.
