Jaeger-LeCoultre DuoPlan “Tank” – 18K Yellow Gold
Circa 1930s–1940s

A remarkable and highly distinctive creation from Jaeger-LeCoultre’s early technical golden age, this Jaeger DuoPlan Tank is a fascinating blend of innovative movement architecture and refined Art Deco design. Crafted in 18K yellow gold and produced during the late 1930s to 1940s, this watch stands out not only for its elegant Tank-style case, but also for its exceptionally rare and ingenious DuoPlan movement.

Large, architectural, and technically daring for its time, this is a true connoisseur’s vintage Jaeger.

The Case – Art Deco Proportions, Unusually Large for the Era

The 18K yellow gold case measures 22 × 35 mm, making it notably large for a watch of this period—particularly for the 1930s and 1940s, when most rectangular watches were significantly smaller. The elongated Tank-style silhouette gives the watch strong wrist presence while remaining elegant and balanced.

The case is fitted with its original gold crown, a highly desirable detail that reinforces the watch’s originality. The overall design is pure Art Deco, with clean lines and refined proportions that reflect the aesthetic sensibilities of the era.

A mineral glass crystal protects the dial, remaining faithful to the watch’s vintage character.

The Dial – Classic Elegance

The watch features a white dial, most likely restored at some point in its life—mentioned with full transparency. The restoration has been executed in a tasteful and period-correct manner, preserving the watch’s vintage charm and legibility.

Complementing the dial are beautiful blue steel hands, adding contrast and a touch of color that enhances the overall elegance of the piece.

The Movement – The Legendary DuoPlan

At the heart of this watch is the famed Jaeger-LeCoultre DuoPlan movement, one of the most interesting and technically inventive calibres of its time. Wound from the back, the DuoPlan features a two-level construction, stacking components vertically rather than spreading them horizontally.

This ingenious architecture allowed Jaeger-LeCoultre to create slim yet mechanically robust movements, and it is precisely this dual-layer design that gives the movement its name: DuoPlan, meaning “two levels.”

Highly complex and far less common than traditional calibres, DuoPlan movements are increasingly rare today and highly sought after by collectors who appreciate early horological innovation.

Strap – Handcrafted Refinement

The watch is fitted with a handmade leather strap from Belgium, offering comfort and a refined finishing touch that complements the watch’s vintage aesthetic.

Good quality, outstanding customer service
The mount is stylish; it looks great in a Tesla. The quality is good. However, the 2025 version broke after 1 year of use, which they fixed in 2026. The customer service is great!

I picked up the Tesla Phone Mount MagSafe Car Mount for my car, and it’s been fantastic. The magnetic strength is impressive — even on bumpy roads my phone stays firmly in place without shifting or slipping. This mount works smoothly with my iPhone (MagSafe cases snap right on), and it’s also easy to use with other phones when I switch drivers. Installation was quick and simple — just stick it where you want it and you’re ready. The mount holds the phone at a great viewing angle for navigation and calls, and I love being able to pop the phone on and off with one hand. The magnets feel strong enough that I don’t worry about the phone falling even during quick turns. Overall, this MagSafe mount has been reliable, secure, and convenient — a great upgrade for everyday driving.

Good Mount / Poorly Connected Magnet
Good product. It fits well on my Model Y screen. It worked fine for 3 months. but then the magnet became loose from the ring. I like the product so instead of discarding it thought of using glue to stick the magnet back to the ring. BUT it didn’t work. So now it has been a frustrating experience. I may choose to discard a product that has a strong mount, but the one important part (magnet) not working correctly.

The best Tesla phone mount
This is a great balance between effective "grabbing of the phone, visibility and a small mount that doesn't get in the way. The whole MagSafe mount sounds great in theory, but depending on the smoothness/slipperiness of the case the phone can bounce out of the mount, which is sub optimal for a variety of reasons. This gives your phone a stable platform while driving, is very durable and is very quick and easy to fit your phone into. It does a good job of attaching to the Tesla display without any messy adhesives and can be easily removed or repositioned without leaving residue. Highly recommended.
