In 1984, the Royal Oak model was presented with a perpetual calendar, not only a rare complication at the time as very few brands were still producing them, but the audacity of housing this delicate complication in a steel sports watch was mind boggling.

Reference 25654 replaced the first Royal Oak Perpetual calendar reference 25554 in 1987 and was produced until 1998 in 315 pieces in steel, 430 pieces in yellow gold, 68 pieces in steel and yellow gold and 38 in platinum. It differs from its sibling for a slightly thicker case thickness (8.25mm vs the 7.5mm of ref. 25554) meant to improve its water resistance capabilities.

However, even though at first glance the present reference 25654 may seem like steel, the acute eye will notice the matte sheen of the metal giving away that it is in fact platinum. Once in the hand, the sheer heft of the watch fully discloses its platinum livery.

Another extremely appealing element is the copper brown dial bearing the traditional Royal Oak tapisserie motif and sunray pattern subdials providing for a very visually powerful result.

An extra element of appeal raising the collectability and desirability of the piece is the fact that it bears number 1 and was retailed by Asprey in London (as engraved on the caseback).

The present reference 25654 is in overall very appealing condition and it is part of a very small number of platinum examples - actually only 38 examples were produced in platinum - with such a graphic dial color.
