	The Morellis 1811 ~~surfaces mainly through specialist dealers and rarely~~ at ~~the major~~ auction ~~houses~~, in line with its ~~modest standing and~~ small production. ~~Documented examples run~~ from the ~~late 1960s into~~ the ~~1970s~~ in ~~yellow gold~~, ~~with~~ the ~~occasional special dial~~. An original Morellis bracelet carries much of the value, since service swaps to plain links are common.		The Morellis 1811 shows up at auction now and then rather than as a regular fixture, in line with its small production. Antiquorum sold a yellow-gold example in New York on 8 December 2016 (Lot 211): a 1967 piece, cal. 1556, satiné silver dial, 36mm case on a President bracelet with textured center links, complete with its original Chronometer Certificate and booklet. The catalogue text calls the bezel finish "moiré crosshatch," which is the primary-source confirmation behind the collector "Morellis" name. Estimated at USD 8,000-12,000, it sold for USD 17,500.

			A second Antiquorum lot, Hong Kong, 28 May 2022 (Lot 211), catalogues a yellow-gold example from around the same period: case no. 1,672,343 by Genex of Geneva, cal. 1555, on a President bracelet the lot text describes as "hammered" rather than moiré. Both lots record a second number stamped alongside 1811 on the caseback (1803 in the 2016 lot, 1601 in the 2022 lot), without further explanation in the catalogue text. Whether "hammered" and "moiré crosshatch" are two words for the same texture or mark a genuine sub-variant is not settled by these two lots alone. Estimated at HKD 95,000-144,000, the piece sold for HKD 115,000.

			An original Morellis bracelet carries much of the value in both cases, since service swaps to plain links are common on surviving examples.

	The 1811 is the Morellis-finish Day-Date. It is a 4-digit President built on the same 36mm gold case and caliber 1555/1556 movement as the fluted [[Reference:1803\|1803]], set apart by a fine watered texture, the moiré or "Morellis" finish, on the bezel and the President bracelet's center links. The finish belongs to the same late-1960s fashion for decorated gold that produced the Florentine 1806 and the bark [[Reference:1807\|1807]]. The Morellis is the rarest and least-seen of the three, made in small numbers and easy to misread, which is why it turns up in listings under several different names.
