Carnival I&W C8887G Open-Heart Automatic Watch — NH36A, 42mm, 50m
The Carnival I&W C8887G is a 42mm automatic dress-sport watch powered by the Seiko NH36A movement — the complete calendar (day, date, week) version of Seiko’s NH-series — with an open-heart aperture showing the balance wheel in motion, genuine sapphire crystal, 50m water resistance and a choice of rose gold or silver-tone case hardware across leather strap and stainless steel bracelet options.
Available in ten configurations spanning rose gold/white, rose gold/blue, rose gold/black, steel/blue, steel/black, steel/white, steel/grey, leather/black, leather/grey and leather/white.
Water resistance clarification: the specification appears in two different places as both 50m/5ATM and 30m/3ATM. Confirm the actual rating with Carnival’s official documentation before publishing. The 50m figure from the detailed spec table is used here as the primary specification.

Variants — Ten Configurations
Rose Gold Case (Leather Strap)
Rose Gold / White: The warmest and most formally elegant configuration. A white dial with rose gold case hardware — the warm rose tone against the light dial creates a watch that reads as contemporary luxury. Paired with leather for dress-watch character.
Rose Gold / Blue: Deep blue dial with rose gold case and leather strap. The warm/cool contrast of rose gold against blue is the most distinctive combination in the range — and in the entire Carnival open-heart collection. For buyers who want a combination that stands out immediately, this is the correct choice.
Rose Gold / Black: Black dial with rose gold hardware. Maximum warmth against maximum darkness — a deliberate high-contrast combination with a dramatic formal character.
Silver/Steel Case — Steel Bracelet
Steel / Blue: Blue dial on silver-tone hardware with stainless steel bracelet. The most sport-dress configuration — blue sunburst and a steel bracelet is the conventional sports watch pairing. Adds wearing weight and solid wrist presence.
Steel / Black: Black dial, silver hardware, steel bracelet. The most formally conservative bracelet option — consistent dark tones appropriate for professional and evening contexts.
Steel / White: White dial on silver bracelet. Maximum legibility — all elements in clear contrast. The most versatile bracelet configuration across contexts.
Steel / Grey: Grey dial on silver bracelet. The most tonally understated of the bracelet variants — grey and silver creates a quiet, refined presence.
Silver/Steel Case — Leather Strap
Leather / Black: Black dial on silver case with leather strap. Clean, high-contrast and versatile.
Leather / Grey: Grey dial on silver case with leather strap. The most subtle configuration overall — restrained in both dial and strap.
Leather / White: White dial on silver case with leather strap. Classic dress watch pairing — the lightest and most formal-adjacent of the leather variants.
Open-Heart Aperture and NH36A
The open-heart aperture reveals the balance wheel in continuous motion — at the NH36A’s 21,600 vph rate the wheel oscillates rhythmically, visible through the dial window. The NH36A’s complete calendar (day, date, week simultaneously) is displayed at 3 o’clock alongside the open-heart display at 6 o’clock — the two features anchor the upper and lower registers of the dial.
The NH36A hacks (seconds stop when crown is pulled) and hand-winds, making precise time-setting straightforward. Complete calendar details are in the Baltany movements guide which covers NH36A specifications in full.
3D Curved Sapphire Crystal
The curved (domed) sapphire creates the lens effect characteristic of vintage professional watches — the dome magnifies the dial slightly at the centre and produces the reflection ring around the bezel edge. The 3D curve differentiates this crystal from the flat sapphire used on simpler models and contributes to the watch’s visual depth.
How It Compares
vs. Carnival I&W Luxury Open-Heart — The I&W Luxury Open-Heart uses Miyota automatic on Italian leather without the NH36A’s complete calendar or the hacking function. The C8887G is the NH36A step-up with complete calendar and hacking.
vs. Carnival Sport Open-Heart — The Sport Open-Heart uses a different movement with small seconds and 24-hour sub-dial at 40mm. The C8887G uses NH36A with complete calendar at 42mm.
vs. Carnival 1986 T6 — The T6 is 42mm with pyramid bracelet, triple calendar and open-heart at 50m. Compare directly — similar specification tier, different bracelet architecture and visual character.
vs. Carnival IW 563 — The IW 563 uses the same NH36A without the open-heart aperture at 41mm with a tungsten bezel and 100m. If the open-heart display is not a priority, the IW 563’s 100m and tungsten bezel are the stronger material specification.
Who Is the Carnival C8887G For?
The C8887G is built for:
- Buyers who want the NH36A’s complete calendar combined with an open-heart balance wheel display
- Rose gold case option buyers — across the Carnival open-heart range, the C8887G and the I&W Luxury Open-Heart are the two models with rose gold hardware
- Buyers who want both a leather strap and steel bracelet available on the same open-heart design
- 42mm open-heart buyers who want hacking seconds for precise time-setting
