Jaeger-LeCoultre REF.6129.21 1970s 18K Yellow Gold Rectangular Model

Sale priceΒ₯500,000

Jaeger-LeCoultre 1970s 18K yellow gold rectangular model 😊

The case is made of 18K gold and has a diameter of 24mm.

Rectangular means "rectangular" in Japanese, but this style is generally associated with the Cartier Tank.

However, looking back in history, Jaeger-LeCoultre and Cartier have a close relationship and there are several similar models.

Jaeger-LeCoultre also supplied a large number of movements to Cartier.

At first glance, this rectangular model looks quite similar, but upon closer inspection there are differences.

First, the case has a stepped bezel that gives it a three-dimensional look.

The dial features a pattern made up of numerous triangles whose vertices are arranged so that they interlock with each other.

This is very beautiful and resembles the traditional Japanese pattern of "uroko."

The scale pattern is said to be so named because it resembles the scales of a fish or snake.

Additionally, the dial on this watch is a highly rare Sigma dial.

At the 6 o'clock position, there is the word SWISS, indicating the country of manufacture, with a Οƒ (sigma) mark on either side.

This denotes the use of precious metals in the dial and/or indices (in this case, the indices) and was only found on special models.

The Sigma mark came to an end around the year 2000, but today it is highly valued among collectors due to its rarity.

Jaeger-LeCoultre's movements are highly accurate and have a history of being used by the world's three major watch brands.

If you understand the background of the brand and wear a Jaeger-LeCoultre watch with a stylish dial and rectangular case, I think you will stand out.


I will measure it again when it comes back from overhaul.


It is in good condition considering its age.

We will update the information again once the overhaul is complete, so please wait a little while longer.

It is scheduled to return from overhaul in mid-May.
