Quick verdict

Only one public claim exists for this reference line, and it concerns the original 6656's value next to comparable perpetual calendars, not this listing. What the listing supports is a 42 × 10.8mm automatic with day, date and month correctors at 2, 4 and 8 o'clock, plus a CNC-machined case. Verify the correctors and timekeeping before you commit.

Only one independent public source; catalog details need verification.

Pros

  • · Listing states a 42 × 10.8mm case — the low-profile proportions it presents for cuff wear.
  • · Hidden correctors at 2, 4 and 8 o'clock set month, date and day; the day can also be advanced with the hands.
  • · Catalog describes CNC-machined case and bracelet, individual QC per piece, and an arched scratch-resistant crystal.

Cons

  • No independently verified downside is available for this item.

Fit notes

Listed at 42mm across and 10.8mm thick. The catalog calls this sizing suited to Asian wrists and slim under a cuff; at 42mm it remains a mid-to-large case, so compare the figures against a watch you already wear before ordering.

Buy if

You want a 42mm calendar automatic where day, date and month are set through recessed pushers rather than the crown, and you accept that the construction and timing descriptions are catalog material — confirm the correctors work and get a timing reading before purchase.

Skip if

You need independent buyer confirmation of accuracy or water performance before spending, or you want a calendar that self-adjusts across leap years; the listing describes day, date and month correction by pusher and says the movement carries most functions.

Buying FAQ

Common questions

What does the listing say about the movement?⌄

It states a cal. 6654-based automatic with low, stable error, and that finished watches run for a day on a Swiss-made simulator before dispatch. That is catalog copy, not an independent measurement.

How are the calendar functions adjusted?⌄

Through recessed correctors: 2 o'clock for month, 4 o'clock for date, 8 o'clock for day, with the day also movable via the hands. Have each corrector actuated before you commit.

Does the listing give a water-resistance rating?⌄

It describes the watch as highly water-resistant but states no depth figure or standard, so the actual rating is unknown. Treat it as unrated until the seller supplies a number.

What does the public record say about this reference?⌄

The only claim found is reader discussion on a watch review calling the original 6656 expensive against comparable perpetual calendars, noting the Jaeger-LeCoultre Master Ultra-Thin steel perpetual calendar at roughly CHF 10,000 less. That is a comment on the original, not on this listing.

What should I check before buying?⌄

Confirm the hidden pushers advance month, date and day correctly, ask for a timegrapher reading or a return window, and measure the 42mm case against a watch you wear.
