Correct Model Identification (Confirmed)
The watch shown is the IWC Portofino Complete Calendar, reference IW359001, the rose-gold variant of the Portofino complete calendar line.
It is often mislabeled in the market as an “annual calendar,” but technically and functionally this is a Complete Calendar, not an annual or perpetual calendar.
Key identifiers that confirm IW359001:
-
40mm Portofino case in rose gold tone
-
White dial with clean radial texture
-
Day + month display with moonphase at 12 o’clock
-
Pointer date subdial at 6 o’clock
-
Roman numerals at 12 and 6 only
-
Leaf-shaped hands with blued central seconds
-
“AUTOMATIC” text centered
-
Classic Portofino case profile
This reference is favored precisely because it offers real calendar utility without turning the dial into a control panel.
Why This GR Version Earns the “Super Clone” Label
Calendar replicas usually fail in one of two ways: fake displays that look right but do nothing, or overbuilt mechanisms that become unreliable with daily use. GR avoids both mistakes by choosing a stable integrated movement architecture and limiting the calendar to what can be realistically supported long term.
All displayed functions are working:
-
Day
-
Date (pointer)
-
Month
-
Moonphase
Nothing is decorative, and nothing is pretending to be perpetual. That honesty matters more than theoretical completeness.
This version qualifies as a super clone because it behaves like a calendar watch over time, not because it claims technical bravado.
Case Proportions and Rose Gold Tone
At 40mm, the case sits exactly where a modern Portofino should. It wears slim and centered, with no top-heavy feeling despite the calendar module.
The rose gold PVD coating is restrained in tone—warm, but not orange. GR avoided the common mistake of overly saturated gold, which tends to look artificial indoors. Under natural light, the case reads soft and elegant rather than flashy.
Polishing is even, with clean transitions along the bezel and lugs. That consistency matters over time, as uneven reflections are one of the first things that betray a replica in daily wear.
Dial Architecture and Calendar Discipline
The dial is where this watch either works or fails—and here it works.
The white dial has a calm, slightly warm character. It is not stark matte white, and it is not glossy. Under indoor lighting, it remains soft and legible; under direct light, the radial brushing appears briefly, then disappears.
Calendar layout is handled with restraint:
-
Day and month at 12 remain compact and readable
-
Moonphase is centered and proportionate
-
Pointer date at 6 aligns cleanly with the minute track
-
Roman numerals anchor the dial without crowding
Nothing overlaps, nothing competes. The eye always returns to the time first, which is exactly how a Portofino calendar should behave.
Crystal and Reflection Control
The watch uses a sapphire crystal with anti-reflective coating. The AR treatment is subtle, avoiding the blue haze that often gives replicas away in indoor environments.
This allows the dial to remain readable and calm under office lighting, which is far more relevant than showroom brightness.
Movement: Imported Miyota 9015 Integrated Calendar Architecture
GR Factory uses an imported Miyota 9015 base movement, modified into an integrated complete calendar architecture inspired by IWC’s Cal. 32150 layout philosophy.
Important practical points:
-
Stable 28,800 bph automatic movement
-
Smooth hand-setting with predictable resistance
-
Functional calendar advancement
-
Month length correction required for short months (as with the genuine)
This is not a stacked decorative module. The choice of 9015 prioritizes reliability, thinness, and serviceability. GR deliberately avoids cosmetic fake bridges that would increase thickness and reduce long-term stability.
That decision favors ownership reality over marketing language.
Strap Material and Wearing Comfort
The watch is fitted with a brown calfskin leather strap with light grain texture and minimal padding. It balances the rose gold case without drawing attention away from the dial.
The strap breaks in evenly and maintains structure, keeping the watch centered during extended wear. Lug width and taper are correct for the Portofino case, avoiding visual imbalance.
Who This Watch Is For
This model is ideal for wearers who want real calendar functionality without visual noise. It suits professional environments, formal settings, and daily rotation where consistency matters more than spectacle.
It is not intended for those seeking perpetual calendar bragging rights or mechanical exhibitionism. This watch rewards calm ownership and regular wear.
