An example rarely seen on the market, only 28 pieces were made in this configuration, with a 37mm 18k white gold case and a black wave-guilloch style dial, as is characteristic of the brand in this era. Another 28 were made for black and white dials respectively, with white gold cases. It elegantly melds the watchmakers love for classic Patek Philippe with an aesthetic that is distinctly his own. The piece features a perpetual calendar with a leap year indicator and a moonphase, all in a comfortably sized case with a self-winding calibre.

Dating from the early 2000s, the Hommage 37 Perpetual Calendar bears the aesthetic hallmarks of early Roger Dubuis, something that was diluted as the brand changed hands starting in the middle of the decade. It is marked by its visual cues that pay homage to classic Patek Philippe, a brand in whose employ the watchmaker spent many years.

An example rarely seen on the market with a 37mm 18k white gold case and a black wave-guilloch style dial, as is characteristic of the brand in this era. Another 28 were made for black and white non-guilloch dials respectively, with white gold cases.

The 37mm case measures 44mm across and stands 11.1mm tall. The dial side is marked by the polished concave bezel which, together with the polished screwed down caseback, sandwiches the brushed caseband. The lugs, in keeping with the finishing, are brushed on the side and polished on top. Integrated into the left of the caseband is the pusher to adjust the perpetual calendar. The crown on the right is well proportioned, easy to use, and signed with the brands mark.

Under the subtly domed sapphire crystal lies the guilloch dial, which features alternating white gold Breguet-style Arabic numerals and arrowhead indices this is in a similar style to the matte black and white versions.However, to accommodate for the more complex dial decoration chosen, the overall layout of information has been very slightly altered. For example, the counter on the outermost chapter ring present on the matte versions has been hugely condensed, allowing the sub-dials and numerals more space. Additionally, the placement of the lettering "Bulletin d'Observatoire" has been moved from above the moonphase to directly above the 12 o'clock marker, integrated into the seconds track itself.

The top half of the dial features twin apertures that display the day and the month, with a leap year indicator located between two and three oclock. The display employs a four-colour disc red for the leap year, yellow for the first year after that, green for the second year, and blue for the third. Also in this half of the dial are the brands mark and horologer genevois, a reference to the watchs Geneva manufacture. The hour and minute hands are of the alpha variety and faceted, while the seconds hand is curved at the end.

The bottom of the dial features the moonphase display, a two-dimensional affair with a rich blue midnight sky and gold stars and moon, with "Quantieme Perpetuel" printed within the "clouds". Beside it is the large radial date indicator with a leaf-style hand. In between the two registers is a Breguet numeral six.

The watch is powered by the Roger Dubuis calibre 5739, which is based on the Longines L990, an automatic winding movement with a 45-hour power reserve. Longines, incidentally is another brand with which Dubuis worked early on in his career as a watchmaker. Visible through the screwed-down display caseback, the calibre is finished with Ctes de Genve, and the winding rotor features a hollowed-out gold insert of the watchmakers signature. The hallmarks of the precious metal the case is forged from are on the underside of the lugs.
