Sourcing & Build
Community verifiedSourcing Notes: Sidereus Watches is an Irish independent watchmaker. Each watch is hand-assembled, regulated, and tested in Ireland in strictly limited runs of 50 pieces per variant. The Newgrange, Dowth, and Knowth Date/Time and Moon Phase models use a modified Swiss-Made Sellita SW200-1 automatic with a custom rotor and élaboré-grade finishing, viewable through a sapphire display caseback. The Réalta GMT uses an under-dial GMT disc with a dual-tone day/night background. Cases are two-part stainless steel (polished, brushed, or vapour-blasted) with sapphire crystals and screw-down crowns rated to 5 ATM. Dials are stepped, slightly domed, with proprietary semi-skeletonised hands. Nice.

Not enough information for a duty figure
The fields above are reported facts. None of them establishes customs origin: that depends on the watch's tariff classification and a substantial-transformation analysis, and what you actually pay also depends on the seller's shipping and duty-payment terms. Ask the seller for the country of origin and whether duties are collected at checkout, and confirm rates against official sources.
