Tourbillons are arguably some of the most challenging watch complications to build by hand. The tourbillon mechanism is tiny and usually crafted with many, many parts, requiring a unique set of tools and a lot of time to produce. This is why they have for so long been expensive and rare, typically costing six figures. ERA Timepieces raised over $1 million on Indiegogo to change that by setting out to make this unique movement attainable for anyone through the ERA Prometheus.
Offering a lower-half exposed mechanism, the ERA Prometheus is a single-axis tourbillon movement that has both a GMT hand and sun/moon-style time-of-day indicator. A 44mm stainless steel case and a sapphire crystal safeguard this intricate movement that is mesmerizing to view. A demonstration of watchmaking virtuosity, it’s an opportunity for anyone to own something that was unattainable for an incredibly long time.
