Explore the F.P. Journe Quantième Perpétuel's unique 'dragged' date change and instantaneous features. Darron's insights reveal the mechanics of this luxury QP.

Darron's insightful post delves into the nuanced mechanics of F.P. Journe's Quantième Perpétuel, highlighting often-overlooked details beyond its well-known instantaneous aperture changes and crown-only setting. His observations on the 'dragged' date change mechanism provide valuable context for collectors appreciating the intricate engineering behind this distinguished reference. This piece offers a deeper understanding of what makes Journe's perpetual calendar truly unique in the horological landscape.

While most are aware of the two features of Journe’s QP that are quite unique is the 1) instantaneous 4 aperture change and the 2) crown only setting of the QP and hidden lug lever to toggle through the 48 months, what i did want to share that some may not be aware of is that the date change is “dragged” , meaning it may not happen exactly at midnight but could occur anywhere from 12:00 to 12:04? I haven’t followed each date change so not sure how much later it could trigger, but it is always instantaneous.

Also, like other QPs, there isn’t a running second hand, so it is not something you do where you are counting down at midnight and NYE and hoping for a perfect instantaneous date change right at 12.

Key Points from the Discussion

The author notes that the instantaneous date change feature, while unique to the Journe QP, is also present in other high-horology pieces like the Lange 1 Perpetual Calendar and Terraluna, though these models typically aim for a date flip much closer to midnight.
An enthusiast expresses admiration for the instantaneous jump features found in watches like the F.P. Journe QP and the Lange 1 Perpetual Calendar, suggesting that such capabilities enhance the overall watch experience.

I’m staying way too far away to be a customer, guess it’s not meant to be. No experience whatsoever with this brand but I like the instantaneous jump features. I think all watches should have this capability. Lange 1 PC is another great example.

are what excited me about the reference. The Lange 1 PC and terraluna have this instantaneous date change feature as well but those two models have a seconds hand and my guess, i have only seen a couple a videos of these that those are intended to flip much closer to midnight (within the first 60 seconds); Curious of the Cubitis grand date instantaneous date change design; though not a QP.

I originally was leaning toward Pt but found the RG case had more warmth. Happy New Year!!
