Hour Wheel 255 (for ETA 2824-2 Sellita SW200 255) H5

This hard-to-find part is for thicker dial builds and repairs! This cerified and precision replacement part is the H5 height variant of Part number 255 (Hour Wheel). It is specifically designed to provide extra hand clearance (about .75mm above the standard H2 factory clearance) on movements utilizing extra-thick dials—such as our the Barger Watch Makers Market .8mm and .6mm brass watch dial blanks, meteorite, aventurine, enamel, or dials with heavily raised markers.

If you are experiencing collisions of hands on the dials or if your minute hand is catching on the dial markers qfter a custom dial swap, this premium H5 pinion is exactly what you need.

Couple this with the 242 H5 Cannon Pinion and Driving Wheel and a long post seconds hand for a complete solution. (One can change out the 4th wheel or seconds wheel to an H5 instead of using a long post seconds hand, however this is a more advanced operation and not recommend without proper watchmaking experience.)

Brand-Specific & Clone Movements

Because the ETA 2824-2 serves as the architecture for many other major luxury calibers and modern equivalents, this component is structurally cross-compatible with:

• Sellita SW200-1 Clones: While Sellita utilizes its own dedicated catalog numbers, a genuine ETA 2824-2 part 242 can mechanically serve as a direct swap into a Sellita SW200-1 or Soprod P024 platform.

• Luxury Caliber Modders: Fits matching base calibers customized by brands, such as the Tudor T601, TAG Heuer Calibre 5, and Breitling Caliber 17.

Buyer Reminder Checklist

• Confirm the "H" Hand Height: Although the part layout remains perfectly compatible among these calibers, the vertical post length must match the height variant (H1, H2, H3, etc.) required by the depth of the dial and hands.
