About this entry

Merges five listings of the NH34 SN0116, all quoted with the same case: SN0116-G-GMT (written "SN0116-G GMT" in its spec list), SN0116-G2-GMT (spec list "SN0116-G1/G2 GMT"; which colour is G1 and which G2 is not stated), SN0116-G-V4, SN0116-G-V5 and SN0116-G-V6. Brand specs: 316L, 39.5mm, 46.5mm lug-to-lug, 12.5mm (not stated whether that includes the crystal), 20mm lugs, top-hat sapphire with AR coating (side not stated, recorded as a box shape), 24-click bidirectional bezel (G-GMT, G2, V4, V6; the V5 does not state its bezel action), applied indices, GMT hand and date window at 6, screw-down crown with hexagon logo, screw-down caseback (brushed on the G-GMT and G2, etched with a dragon on the V5), seven-link solid 316L bracelet 20mm tapering to 16mm (beads-of-rice in the photos) with the "New Fly Adjustable Clasp" (on-the-fly; positions and range not stated), 100m. Differences by version: the G-GMT has a ceramic bezel with full lume and BGW-9 lume; the G2 has a ceramic world-timer bezel with city names (photos) and BGW-9 blue plus C3 green lume; the V4 and V6 have aluminium inserts in Pepsi-style blue/red or brown with BGW-X1 lume and sword hands, the V6 with an aged-effect print on dial and hands; the V5 "2024 Year of the Dragon Limited Commemorative Edition" has a red cloud-pattern dial with the character for dragon, a red ceramic bezel with the Twelve Earthly Branches in place of the 24-hour numerals, pencil hands and "BGW blue lume" (number made not stated; its option list also shows "Black" and "Green" dial colours, which do not match the description or photos). Weight about 134g on the G2 and "about 136" on the G-GMT (not stated what was weighed). The G-GMT is also offered on a nylon strap and the V6 on a leather strap; strap widths and buckles are not stated. Every listing showed "Out of stock" on 2026-10-25, so production status is unknown. The NH35 diver (sn0116-nh35) and VK64 chronograph (sn0116-vk64) use the same 39.5mm case family.
