Replica grand complication 720.025 watches are multi-function dress pieces that copy a high-end perpetual calendar layout. The short answer: judge one by four things, case dimensions measured with calipers, calendar and moonphase alignment, movement finish under magnification, and how the subdials track across 48 hours of running time. Listings that skip those four points do not hold up in hand.
What the 720.025 Replica Normally Reproduces
Most versions on the market follow the same template. Quality tiers differ in the calendar mechanism, the dial construction and the case metal.
- Subdials for day, date, month and leap year
- Moonphase aperture with a printed or applied disc
- 24-hour or day and night indicator
- Case size between 39 mm and 41 mm, steel with plating on entry tiers, solid gold on top tiers
- Hand-wound or automatic movement behind a display back
- Deployant or pin buckle on an alligator-pattern strap
Prerequisites
- Digital calipers and a 10x loupe
- A timegrapher, or a phone app that reads beat rate and amplitude
- A written return window of at least seven days
- Your wrist measurement in millimeters
How to Inspect a 720.025 Replica, Step by Step
- Measure the case across 12 to 6 with calipers and compare the result to the listing.
- Measure lug to lug, then rest the watch on your wrist to confirm the lugs do not overhang.
- Weigh the watch on a kitchen scale to confirm the case is not hollow.
- Examine the dial at 10x, checking that the logo, minute track and subdial rings are crisp and level.
- Inspect the crystal edge for a domed sapphire profile and an inner anti-reflective coating.
- Advance the date one day at a time and confirm the jump lands within a few minutes of midnight.
- Advance the day, month and leap-year indicators one at a time and confirm each snaps instead of drags.
- Rotate the moonphase disc through a full cycle and check that the aperture edges stay clean.
- Wind the movement until resistance, then let the watch sit untouched for 48 hours to confirm the stated power reserve.
- Time the rate in six positions on a timegrapher and note the spread between them.
- Press each corrector with a toothpick and confirm it returns to rest.
- View the caseback under magnification and check for burred screw slots, uneven perlage and stray dust.
Red Flags
- One pusher driving several calendar functions with no detents
- Printed subdials sitting on a flat, non-recessed dial
- Screw slots with chewed edges or plating flaking at the corners
- Water resistance claims above 30 m on a dress case with no gasket documentation
- Product photos from a single angle only
Care and Servicing
Keep the watch away from water, steam and perfume, since the gaskets on a calendar case are the first parts to fail. Wind it at the same time each day to keep the calendar train under tension, and set the date with the crown pulled to the correct position rather than by nudging the hands backward. An annual check of the rate is enough for most owners, with a full service every three to five years depending on how often the calendar functions get used. Store it on a soft pad so the correctors do not take pressure in a drawer.
