Marteau & Co’s The Encore online auction runs October 8–15, 2026. Its 42-lot catalogue includes a Yosuke Sekiguchi Primevère “Interprétation du Japon” and a Voutilainen Vingt-8 with an additional bespoke dial, both described by the house as unique pieces. Five F.P.Journe 38 mm steel watches and a numbered Coffret presentation box appear as separate lots. Bidding was open at our October 12 check; displayed bids are not completed-sale results. The conditions specify a 20% buyer’s premium, with 3% of the hammer price redistributed from that premium to the original watchmaker or a designated watchmaking nonprofit. Applicable VAT and other charges are additional.
