Last reviewed 2026-10-06: every specification below was read on each maker's own product page that day.
Buy the San Martin SN058-G-X if you want Datejust 36 proportions; buy the Pagani Design PD-1645 if you want a larger 42 mm watch you can order in more colours today. San Martin's own spec sheet states 36.5 mm across and 43 mm lug to lug for the SN058-G-X. Pagani Design's own page states 42 mm across for the PD-1645. On the published fidelity rubric the SN058 scores 85 and the PD-1645 scores 72, and case size is most of that gap.

San Martin SN058-G-X: the 36 mm one San Martin ↗
The SN058-G-X is the only watch of the two built near the original's size: 36.5 mm across, 43 mm lug to lug and 11.9 mm thick. You choose the movement at order, a PT5000 or an SW200 automatic. It has a carved steel bezel, a 5-link bracelet and a screw-down crown. Availability is the catch. On 2026-10-06, San Martin's store showed 1 of its 24 configurations in stock: PT5000, Sunray Black, with logo. Every SW200 configuration was out of stock.

Pagani Design PD-1645: the bigger, easier one to buy Amazon ↗
The PD-1645 has a fluted bezel in two finishes, a jubilee bracelet, a cyclops date, sapphire and a 100 m rating. Its case is 42 mm, six millimetres over a Datejust 36, and Pagani does not publish its lug-to-lug length. On 2026-10-06, all 9 colour variants on Pagani Design's own store were listed as available.
SN058-G-X or SN058-G: check the suffix

Sources: San Martin, SN0058-G-X page and San Martin, SN0058-G page, both read 2026-10-06. San Martin notes that its SN058-G figures come from manual measurement and can contain errors. The store URLs spell the model "SN0058"; the specification block on each page says SN058-G-X and SN058-G.
The PD-1645 movement: one name on the maker's page, check the listing
Pagani Design's own PD-1645 page names the Japanese Miyota 8215 automatic in its page title and description. Its specification list says only "Automatic" and names no calibre. You may see the PD-1645 described elsewhere with a Seiko NH35A. Pagani Design's own page does not say that, and no second source could be read for this page on 2026-10-06, so the table shows only what Pagani Design states. Before you buy, check the calibre on the exact listing you order from.
The bracelet and clasp note
- PD-1645: Pagani Design says the jubilee bracelet links come out with a 1.2 mm screwdriver and that the folding clasp has 2 positions (Pagani Design, PD-1645 bracelet page). The PD-1645 page itself recommends professional help for steel link removal (Pagani Design, PD-1645 page).
- SN058-G-X: San Martin lists a hidden clasp with its hexagonal logo, but publishes no sizing or micro-adjustment detail (San Martin, SN0058-G-X page).
Who should choose which
- Choose the SN058-G-X if the 36 mm Datejust size matters, if your wrist is small to medium, or if you want the PT5000/SW200 movement choice. Accept that few configurations are in stock.
- Choose the PD-1645 if you prefer a 42 mm case, want a wide choice of dial colours that are available now, or want a 3-year warranty from the official store.
- Choose neither if you want 36 mm and the SN058-G-X configuration you like is out of stock. See the full Datejust homage ranking for other sizes.
