Caliber designations (Source: Uhren Wiki / Stephen Foskett)

Jaeger-LeCoultre uses numbers to identify its calibers. There is a rough system for numbering, with smaller calibers receiving lower numbers and larger and more expensive calibers receiving higher numbers. Jaeger-LeCoultre also tends to use similar numbers for related calibers, although this is not always the case. In most cases, variants of a base caliber of the same generation receive numbers from the same decade, while major revisions receive a new decade. For example, caliber 889 was replaced by caliber 899, and variants of the latter included calibers 896 and 898.

The prefix letters generally refer to shock-absorbing systems, although these are rarely used today. "P" stood for Parachoc , while "K" stood for Kif .

Numerical suffixes indicate minor revisions, as is the case with other movement manufacturers. For example, some Jaeger-LeCoultre calibers have a "/2" variant when changes were made that did not require a new caliber number.

Suffixes indicate complications or features: "SQ" stands for a skeleton ("squelette"), while other letters often denote complications, certifications, or applications. The Caliber K880G, for example, was a chronometer-certified version of the Caliber 880 with Kif shock protection.
