The stainless-steel Jaeger-LeCoultre Master Control Chronometre Date (Q4158120) keeps its display to hours, minutes, seconds and date. Its 38 mm case, 8.4 mm thickness and 70-hour power reserve make it the most restrained complication choice among the documented Master Control Chronometre models here. That simplicity is a matter of taste, not an objective ranking: the right choice depends on whether you prefer a clear time-and-date display or want additional indications.
What the Master Control Chronometre Date offers
Jaeger-LeCoultre specifies Q4158120 in stainless steel with an integrated steel bracelet and a blue-grey gradient sunray dial. The automatic Manufacture Calibre 899 displays hours, minutes, seconds and the date. The manufacturer lists a 70-hour power reserve and a frequency of 4 Hz. See the official Q4158120 specifications.

- Case: 38 mm in diameter and 8.4 mm thick.
- Water resistance: 5 bar, as specified by the manufacturer.
- Movement: automatic Calibre 899, which Jaeger-LeCoultre describes as COSC-certified.
- Display: hours, minutes, seconds and date.
Those are manufacturer specifications, not independent measurements. The compact set of indications is the basis for calling this the simpler option; it does not establish that the watch will fit every wrist or be easier to read for every wearer.

Jaeger-LeCoultre says its High-Precision Guarantee (HPG) tests both calibres and complete cased watches over three days of simulated daily wear. The company describes test conditions that include wrist positions, pressure, temperature variations and shocks. This is the manufacturer’s account of its protocol; the materials cited here do not independently assess the testing method or establish comparative accuracy against other watches. The 2026 launch release provides further context on the collection and the HPG Seal: Jaeger-LeCoultre’s Master Control Chronometre introduction.

How the Date compares with other Master Control Chronometre models
The Date is the simplest documented complication set among these models. The alternatives add either a power-reserve display or a perpetual calendar and moon phase; the pink-gold Date keeps the same core functions while changing the case and dial materials.
| Model | Case and material | Movement and display | Power reserve |
|---|---|---|---|
| Date Q4158120 | 38 × 8.4 mm; stainless steel | Calibre 899; time and date | 70 hours |
| Date Q415216J | 38 × 8.4 mm; 18K pink gold | Calibre 899; time and date | 70 hours |
| Date Power Reserve Q4168120 | 39 × 9.2 mm; stainless steel | Calibre 738; time, date and power-reserve indication | 70 hours |
| Perpetual Calendar Q4178180 | 39 × 9.2 mm; stainless steel | Calibre 868; perpetual calendar and moon phase, plus time | 70 hours |
Jaeger-LeCoultre describes the pink-gold Date as having a bronze-coloured dial. Its display is otherwise the same core time-and-date configuration as the steel Date. The Perpetual Calendar product page says its calendar is accurate until 2100; that is the manufacturer’s stated claim.

Which version suits your priorities?
- Choose the steel Date if you want the most pared-back display in this comparison and prefer its blue-grey dial and steel construction.
- Consider the pink-gold Date if you want the same time-and-date functions in a precious-metal case and bracelet with a bronze-coloured dial.
- Consider the Date Power Reserve if you value seeing the power reserve on the dial and accept a 39 mm case that is 9.2 mm thick.
- Consider the Perpetual Calendar if a more information-rich display and calendar complication matter more to you than simplicity.
These distinctions describe specifications, not a wrist-fit or legibility test. Try the case and bracelet if possible, and decide whether the added indications are useful to you rather than choosing on complication count alone.
