The Heart of the Watch

A watch movement is more than just a timekeeping mechanism – it's the soul of the timepiece. Understanding different movements helps you make informed decisions about your watch purchases.

ETA Movements

Swiss-made ETA movements are the industry standard for reliability and serviceability. The ETA 2824-2 and 2892-A2 are found in watches ranging from affordable to luxury price points.

Seiko Movements

Miyota Movements

Citizen's Miyota movements provide excellent performance at competitive prices. The 9015 is particularly popular for its slim profile and reliability.

Choosing the Right Movement

Consider your priorities: Swiss heritage, Japanese reliability, or value for money. Each movement family has its strengths and ideal applications.
