A. Lange & Söhne is not content to update an existing model by simply expanding the watch’s case metal options, a tactic frequent among even the world’s finest watchmakers. We often see an existing model from this famed German watchmaker updated with a new movement, an updated dial treatment or even an entirely new case size.
So yes, the new A. Lange & Söhne Zeitwerk Honeygold Lumen, as its new name signifies, is newly draped in the watchmaker’s own warm-hued Honeygold alloy, the first time we’ve seen a Lumen watch cased in Honeygold.
But it should also surprise no one that the newest edition of one of A. Lange & Söhne’s most spectacular watches hosts several technical updates, in addition to its namesake new case metal.
Longer power reserve
The new watch also boasts Caliber L043.9, a new movement iteration. A. Lange & Söhne has updated the movement with a 72-hour power reserve, doubling the reserve of its predecessor model. This extends the operating time as it powers Zeitwerk’s three-disc jumping digital numerals mechanism.
A. Lange & Söhne has also heightened the caliber’s stability by adding a (patented) constant-force escapement to control the time display’s complex switching processes. As the watchmaker explains, the newest escapement generates the impulse for the jumping time display while also “drives the balance with nearly uniform power across the entire run time.”
The pusher at 4 o’clock is also new. This allows the hour indication to be separately switched, which makes setting the time quite a bit simpler.
And as the newest Lumen model in a series dating to the first Zeitwerk ‘Lumious’ from 2010, the Zeitwerk Honeygold Lumen employs the watchmaker’s specially developed light-permeable dial coating. This means all the numerals on the digital time discs – even those not visible on the dial – will absorb enough light needed to make them glow in the dark.
As you might expect from any watch leaving Lange headquarters Glashütte, this 41.9mm watch is finished to perfection. You’ll find hand-engraved balance and escape-wheel cocks, sunray-pattern winding wheels and filigreed, straight-grained constant-force escapement bridge that accommodates two recessed, screwed gold chatons.
Limited to 200 watches, the A. Lange & Söhne Zeitwerk Honeygold Lumen is attached to a handsome dark-brown leather strap. Price: $145,000.
