Jaeger-LeCoultre Master Perpetual Calendar Automatic Watch

It seems like you've provided a detailed overview and comparison of the Jaeger-LeCoultre Master Perpetual Calendar Automatic Watch (official models: white face 130842J, black face 1308470, gold face 1302520, grey face 130354J), famously worn by Stephen Strange in the movie "Doctor Strange". Here’s a summary of its features and buying reasons:

### Features:

1. **Perpetual Calendar**: Displays the year continuously from 2017 to 2024, with the option to adjust through a hidden button on the case. Unlike the original, adjustments are reversible (original adjustments require paid servicing once set).

2. **Day, Month, Year Display**: Located at 3 o'clock, 6 o'clock, and 9 o'clock respectively. Each can be manually adjusted for precise timekeeping.

3. **Warning Window**: Positioned above the central pin axis on the dial, it indicates white for manual adjustment of the year and blue for restricted periods to prevent damage to the movement.

4. **Moon Phase Indicator**: Positioned at 12 o'clock, displaying moon phases over a 24-hour cycle.

5. **Timekeeping**: Functions like a regular watch for hours, minutes, and seconds.

### Buying Reasons:

1. **Comprehensive Functionality**: Includes all features of a perpetual calendar, making it highly functional and visually appealing.

2. **Close Resemblance**: The design closely mimics the original due to precise molding, achieving a 98% similarity in dial appearance, font distribution, and overall quality.

3. **Practical Size**: With a 39mm diameter, it suits both formal and casual attire.

4. **Dauphine Hands**: Features Jaeger-LeCoultre's signature hands (half-sandblasted, half-polished), distinguishing it from ordinary models.

5. **Reasonable Price**: Offers high value compared to other complex-function watches, making it accessible to many.

### Issues:

1. **Thickness**: Slightly thicker than the original at 11.5mm (original is 9.2mm), though not easily noticeable to the naked eye.

2. **Movement Structure**: Differences in movement structure affect similarity, with benefits including superior year adjustment (V9 allows reversible adjustment, original does not).

3. **Moon Phase Accuracy**: While functional, the moon phase cycle differs slightly (24 hours vs. 30 days), though it does not impact appearance or usability.
