Correct Model Identification (Confirmed)
The watch shown is the IWC Portofino Complete Calendar, reference IW359001, in the rose-gold tone and white dial configuration from the Portofino complete calendar line.
It is sometimes described in the market as an “annual calendar,” but this listing should be read as a Complete Calendar, not an annual calendar, perpetual calendar, or simple moonphase model.
Key identifiers for IW359001 include:
-
40mm Portofino case in rose-gold tone
-
White dial with clean radial texture
-
Day and 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 hand
-
“AUTOMATIC” text centered on the dial
-
Classic Portofino dress-watch case profile
This reference is best understood as a restrained calendar watch: it gives the wearer day, date, month, and moonphase information while keeping the dial visually ordered.
GR Factory Complete Calendar Execution
GR Factory’s version is focused on practical calendar operation rather than decorative calendar imitation. The listing describes an imported Miyota 9015 base movement modified into an integrated complete calendar architecture, with the visible calendar indications arranged around the IW359001 dial layout.
The stated displayed functions are:
-
Day
-
Pointer date
-
Month
-
Moonphase
Nothing in this listing should be read as a perpetual-calendar or annual-calendar claim. Month correction is required for short months, so buyers should treat this as a working complete-calendar replica with normal manual calendar attention.
Case Proportions and Rose-Gold Tone
At 40mm, the case follows the modern Portofino dress-watch profile: broad enough for the calendar layout to remain readable, but still formal in presentation. The rose-gold tone is an important QC point because this colorway depends on restraint. In review photos, buyers should look for a warm case tone that does not appear overly orange or uneven across the bezel, lugs, crown, and case flank.
Case finishing should be checked through reflection lines. The bezel edge, lug transitions, and polished surfaces should look consistent from photo to photo, especially under direct light where uneven polishing is easier to notice.
Dial Architecture and Calendar Discipline
The white dial is described with a clean radial texture and a calm calendar layout. The design places the main calendar cluster at 12 o’clock, with day and month windows above the moonphase display, while the pointer date sits at 6 o’clock. Roman numerals at 12 and 6 help anchor the dial without filling every hour position.
Important dial checks include:
-
Day and month at 12: confirm the text sits centered in the display windows
-
Moonphase: check that the disc sits evenly and does not appear tilted or crowded
-
Pointer date at 6: verify that the hand points cleanly to the printed date scale
-
Roman numerals: inspect placement, spacing, and printing sharpness at 12 and 6
-
Hands: check the leaf-shaped hour and minute hands and the blued central seconds hand for clean finishing
The goal of this layout is legibility first. The calendar information should be readable without making the dial feel crowded.
Crystal and Reflection Control
The watch is described with a sapphire crystal with anti-reflective coating. For this model, the useful QC check is not only clarity, but reflection behavior. Ask for angled dial photos so the crystal can be checked for excessive haze, strong color cast, or reflections that obscure the day, month, moonphase, or pointer date displays.
Because the dial is white, crystal reflections can affect how cleanly the calendar details read in office or indoor lighting.
Movement: Imported Miyota 9015 Integrated Calendar Architecture
GR Factory uses an imported Miyota 9015 base movement adapted for the complete calendar layout. The practical value of this architecture is that the day, pointer date, month, and moonphase are presented as functional indications rather than fixed decorative elements.
Buyer-facing movement points:
-
Imported Miyota 9015 base movement is stated
-
Integrated complete calendar architecture is stated
-
Displayed functions are day, pointer date, month, and moonphase
-
Month correction is required for short months
-
Power reserve, decoration details, and service procedure are not specified in the provided product data
During QC, confirm smooth crown operation, hand setting, and calendar advancement where video or handling confirmation is available.

Inspection Cautions
Calendar replicas should be reviewed carefully because small alignment issues are easier to see on a white dial. The most important areas are the day and month windows, moonphase centering, pointer date positioning, and dial printing around the lower date scale.
Rose-gold tone also deserves attention. A restrained warm tone suits this IW359001 layout, while excessive orange saturation or inconsistent coating can change the character of the watch. Crystal reflection color, strap finishing, and crown feel should also be checked before confirming the configuration.
Because this is a complete calendar, short-month correction remains part of normal use. Buyers who prefer a set-and-forget calendar should consider that before choosing this layout.
Who This Watch Is For
This model suits buyers who want a formal-leaning Portofino replica with visible calendar utility and a calm white dial. It fits professional environments, dress use, and daily rotation where balanced proportions and legibility matter more than a sport-watch profile.
It is less suitable for buyers who want a simple no-date watch, a sports-style case, a perpetual-calendar claim, or an openworked movement presentation. The appeal here is the complete calendar layout, rose-gold tone, and restrained Portofino design language.

Inquiry Guidance
For this GR Factory IWC Portofino Complete Calendar IW359001, request current QC photos that clearly show the white dial, rose-gold tone case, day and month windows, moonphase display, pointer date subdial, crown side, case finishing, crystal reflections, and brown calfskin strap fitment.
Use those photos to confirm the complete calendar layout and preferred configuration before proceeding.
Design Background
The GR Factory IWC Portofino Complete Calendar IW359001 replica is best read as a formal Portofino calendar watch, not an annual calendar or a simple moonphase model. Its appeal comes from the IW359001 layout: a 40mm rose-gold tone case, white radial dial, day and month display at 12 o’clock, moonphase at 12 o’clock, and pointer date at 6 o’clock. The Roman numerals at 12 and 6, leaf-shaped hands, and blued central seconds hand keep the dial restrained while still giving the buyer visible calendar information.
This rose-gold tone and white-dial version suits buyers who want a warmer dress-watch profile without moving into a sportier or more decorative look. The brown calfskin leather strap with light grain texture and minimal padding supports that formal direction, while the classic Portofino case shape keeps attention on dial balance, calendar alignment, and case tone control. Case thickness is not specified in the provided product data, so buyers should use side-profile QC photos to judge how the watch sits visually.
GR Factory’s stated movement approach is an imported Miyota 9015 base adapted into an integrated complete calendar architecture. The buyer-useful point is simple: the listed day, pointer date, month, and moonphase indications are presented as functional calendar displays, with month correction required for short months. This should not be expanded into a perpetual-calendar or annual-calendar claim.
The sapphire crystal with anti-reflective coating matters on this version because the white dial exposes reflections and printing detail clearly. Before comparing it with other Portofino replicas, buyers should focus on day and month window centering, moonphase disc position, pointer date alignment, rose-gold tone consistency across the bezel, lugs, crown, and case flank, plus strap fitment at the lugs. This version attracts buyers who want a calm complete-calendar replica with practical dial utility rather than a heavily complicated or openworked presentation.

Watch Evaluation Highlights
GR Factory IW359001 Version
This listing should be evaluated as the IWC Portofino Complete Calendar IW359001 in rose-gold tone with white dial, not as an annual calendar or perpetual calendar. The key identification points are the day and month at 12 o’clock, moonphase at 12 o’clock, and pointer date at 6 o’clock.
Integrated Calendar Movement
The stated movement is an imported Miyota 9015 base adapted into an integrated complete calendar architecture. Buyer checks should focus on whether the day, pointer date, month, and moonphase indications advance and align correctly, with short-month correction expected.
40mm Dress Case Profile
The 40mm rose-gold tone case gives the calendar dial enough space while keeping the Portofino layout formal rather than sporty. Case thickness is not specified, so side-profile QC photos are useful for judging wrist presence and case proportion.
White Dial Calendar Layout
The white radial dial makes alignment easy to inspect. Check day and month window centering, moonphase disc position, pointer date accuracy, Roman numeral placement at 12 and 6, minute track spacing, leaf-hand finishing, and the blued central seconds hand under clear lighting.
Crystal and Tone Control
The sapphire crystal is described with anti-reflective coating, so angled photos should confirm that reflections do not obscure the calendar displays. The rose-gold tone should also be checked across the bezel, lugs, crown, and case flank for consistent warmth without excessive orange saturation.
Brown Calfskin Strap Fit
The brown calfskin leather strap with light grain texture and minimal padding supports the restrained dress-watch profile. QC photos should show strap fitment at the lugs, stitching consistency, edge finishing, and how evenly the strap sits against the case.
Known Flaws
- Calendar display alignment: Inspect the day and month windows at 12 o’clock, the moonphase aperture, and the pointer date scale at 6 o’clock. These areas matter because the white dial makes small centering errors easy to notice; for most buyers, slight offset is acceptable, but obvious misalignment should be treated as a meaningful QC concern.
- Dial printing and Roman numeral placement: Check the radial dial texture, minute track spacing, printed date scale, and Roman numerals at 12 and 6 for sharpness and even positioning. This matters because the IW359001 layout depends on visual balance rather than heavy decoration; minor print softness is usually low severity, while crooked markers or uneven spacing are more visible.
- Rose-gold tone consistency: Compare the bezel, lugs, crown, and case flanks under the same lighting. The rose-gold tone should look restrained and consistent; a slightly warm variation is normally not a major issue, but an overly orange tone or uneven coating can change the dress-watch character of this version.
- Crystal reflection behavior: Review angled QC photos for haze, color cast, or distortion from the sapphire crystal with anti-reflective coating. This matters because reflections can obscure the day, month, moonphase, or pointer date displays; for most buyers it is a moderate concern only if legibility is affected in normal light.
- Hand finishing and alignment: Inspect the leaf-shaped hour and minute hands, the blued central seconds hand, and the pointer date hand for clean finishing and accurate pointing. Small finishing marks are usually low severity, but a pointer date hand that misses the printed scale or hands that appear poorly aligned should be checked before confirming.
- Strap fit and case profile impression: Check how the brown calfskin strap sits between the lugs, along with stitching, edge finish, and side-profile case thickness appearance. Strap finishing is usually a lower-severity issue for most buyers, but poor lug fit or a visually thick case profile can affect the formal Portofino wearing profile.
Portofino models tend to highlight factory differences through dial printing and overall visual harmony. IWC Portofino replica guide.
