ZEITWERK MINUTE REPEATER
The two hammers made of black-polished steel are positioned on both sides of the subsidiary seconds dial, making it possible to observe how the sound is produced. Contrary to the ZEITWERK STRIKING TIME models and the ZEITWERK DECIMAL STRIKE HONEYGOLD, the gongs are arranged along the black-rhodiumed German silver time bridge. That is why here, the hammers face inward. The complex gong tuning process is performed exclusively by hand. It requires a trained ear to make sure both gongs produce a clear and reverberating sound in their final positions in the case.
