Reference:118238 - Revision history

Admin: Fact fix: 118238's COSC re-certification claim was internally inconsistent with its own 2015-2019 production window — caliber 3155 was re-regulated catalogue-wide in 2015 mid-run, so late 118238 examples carry the tighter Superlative Chronometer ±2 spec, not a blanket pre-2015 rating (per Monochrome, cross-checked via daydate-d's 118239 research)

	~~The 118238 is the last Day~~-~~Date generation~~ to ~~ship without~~ the Superlative Chronometer ~~2015 re-certification. The 128238 successor and the broader post-2015 Rolex catalogue carries the tighter~~ ±2-seconds-per-day ~~spec;~~ 118238 examples ~~remain at~~ the older COSC ±4 / +6 ~~standard~~.		Rolex re-regulated caliber 3155 catalogue-wide to the tighter Superlative Chronometer ±2-seconds-per-day standard in 2015, mid-way through the 118238's own production run, which continued to 2019. Early 118238 examples carry the older COSC ±4 / +6 certification; examples cased from 2015 onward should carry the tighter ±2 spec, the same movement upgrade the 128238 successor inherited at launch.
