The IWC Portugieser Chronograph IW371620 pairs a 41 mm stainless-steel case with a white dial, blue subdials and a blue rubber strap. Its automatic Caliber 69355 provides a 46-hour power reserve, while the watch’s 3 bar water-resistance rating is modest. IWC introduced the model on 15 August 2022; its current regional prices and availability should be checked locally.
What “Blue Panda” means on the IW371620
“Blue Panda” is a descriptive nickname for this reference’s white dial and contrasting blue subdials, not the official model name. IWC calls the dial white with contrasting blue subdials. In its 15 August 2022 launch release, the manufacturer noted that watch enthusiasts often refer to dials with strong contrast between the main dial and subdials as “panda” dials.
The blue details extend to the feuille-shaped hands and the factory-fitted blue rubber strap. The chronograph minutes counter is at 12 o’clock, while the small-seconds display sits at 6. That arrangement is useful to note when comparing it with chronographs whose elapsed-minute and running-seconds displays occupy different positions.

Movement and everyday implications
IWC lists the automatic Caliber 69355 with a 46-hour reserve and describes its chronograph as a column-wheel design. The reserve is the manufacturer’s stated figure; it is not a measure of the watch’s timekeeping accuracy. No accuracy result is established here.
The 3 bar water-resistance specification is not a basis for recommending swimming or diving. Treat it as a modest rating and follow IWC’s guidance for water exposure and maintenance rather than assuming that the watch is suitable for a particular activity.

The 41 mm diameter and 13 mm height are useful starting points for fit comparisons, but dimensions alone do not establish how a watch will sit on a particular wrist. Likewise, the blue rubber strap may appeal to someone seeking a sportier material than leather, but no firsthand comfort or hot-weather assessment is available.
Regional price and availability
IWC’s EU product page showed a price of €9,400 including VAT when accessed in 2026. IWC’s Canadian product page showed CAD 12,100 before VAT at the same research time. These are separate regional listings with different tax bases, not directly comparable all-in prices or a universal price. Check the local IWC listing for a current quote and confirm stock with the seller.
Rank #3
A Japanese retailer, Jewelry Paris, listed the reference at ¥1,457,500 including tax when indexed. That is a retailer’s localized listing, not an official global price. See the Jewelry Paris listing and confirm its current terms directly.
IWC announced the model as available through its boutiques, authorized retail partners and IWC.com at launch in 2022. That announcement does not establish present inventory. For current listings, consult IWC’s EU page or Canadian page, then verify availability and final pricing in your market.

Warranty and service checks
IWC’s product page describes a standard two-year International Limited Warranty and a complimentary six-year extension through My IWC care registration, provided registration occurs while the original warranty is still active. That can bring potential coverage to eight years; eligibility and terms should be confirmed for the buyer’s region. Ask the seller how warranty coverage applies to the specific watch and what service arrangements are available.

Compare like with like: automatic chronographs in a similar price range and intended use. Check the practical distinctions below rather than relying only on dial color or brand positioning.
Best Value
- IWC Pilots Chronograph APXGP Automatic Black Dial Men's Watch IW378009
- Case fit: Compare diameter and thickness with a watch you know fits you; this reference is listed at 41 mm by 13 mm.
- Dial and counter layout: Decide whether the white-and-blue contrast is easy for you to read, and check that the chronograph minutes at 12 and small seconds at 6 suit your preferences.
- Movement: Compare the stated reserve, frequency and chronograph architecture. For the IW371620, IWC specifies 46 hours, 28,800 vph and a column-wheel design.
- Strap compatibility: The factory strap is blue rubber and 20 mm wide, but width alone does not establish that a generic replacement will fit the case correctly. Confirm end shape and compatibility before buying another strap.
- Water resistance: Compare the manufacturer’s rating with your intended use; this model is rated at 3 bar, without a swimming or diving recommendation established here.
- Ownership support: Compare current local quotes, seller authorization, warranty eligibility and service arrangements—not just a displayed price.
What is and is not established
The manufacturer’s specifications and launch description establish the reference’s listed dimensions, movement details, dial configuration and water-resistance rating. They do not establish measured accuracy, low-light legibility, long-term durability, wrist comfort, service costs, current street price or present inventory. IWC’s 2023 product video is available on IWC Watches’ YouTube channel, but it should not be treated as an independent hands-on test.
