A highly relevant example within the late production run of the classic no-date Submariner, this U7 serial sits at the very end of the transitional period that defines the reference’s most collectable configuration.

The U serial production window is particularly significant because it represents the final phase of manufacture still fully aligned with the traditional architecture: tritium dial (T<25), classic two-line layout, and the calibre 3000 in its original non-COSC execution. This combination marks the closing chapter of the “pre-modern” Submariner identity before luminova adoption and subsequent industrial refinements.

From a collector’s standpoint, U serial tritium examples are increasingly regarded as structurally coherent pieces rather than transitional compromises. The lume application remains factory-original tritium, now aged consistently, while the dial layout preserves the purest aesthetic balance of the 14060 lineage.

The inclusion of box and warranty further strengthens the positioning, as it confirms preservation within its original delivery context, a factor that materially improves both traceability and market perception.

Overall, this configuration represents one of the most desirable expressions of the late 14060: a fully mechanical, non-COSC Submariner retaining tritium integrity and pre-modern production character at the very edge of its historical production cycle.
