BLS Factory IWC Pilot 41mm – EasX-CHANGE and 69385 Movement Guide
The BLS Factory IWC Pilot 41mm takes the familiar Pilot’s Watch design and brings it into a more compact 41mm case format.
Compared with the larger 43mm configuration, the 41mm size gives the watch a noticeably more compact presence on the wrist. Another important change is the 20mm strap width, rather than the 21mm format associated with the larger case.
What makes this release particularly interesting, however, is the combination of the smaller case with an EasX-CHANGE-style quick-change system, allowing compatible steel bracelets, leather straps and rubber straps to be removed without conventional strap-changing tools.
41mm Case and 20mm Strap Width
The supplied specifications list a 41mm case with a 20mm strap width.
This is an important distinction from some earlier or larger Pilot configurations using a 43mm case and 21mm strap width.
The smaller dimensions change the way the watch sits on the wrist. A Pilot’s Watch traditionally has a relatively strong visual presence because of its large dial, clear numerals and broad case profile, so reducing the case to 41mm can make the overall proportions easier to wear for a wider range of wrist sizes.
Both stainless-steel and ceramic configurations are referenced in the supplied release.
EasX-CHANGE Quick-Change System
One of the most useful features of this BLS 41mm version is its EasX-CHANGE-style strap system.
The quick-release construction is designed to allow the bracelet or strap to be detached by hand without using a traditional spring-bar tool.
This makes it possible to switch between compatible:
Steel Bracelet → Leather Strap → Rubber Strap
without treating every strap change as a watchmaking job.
For anyone who regularly changes the appearance of a watch, this is a genuinely practical feature rather than simply a visual detail.
The quick-release mechanism should still be checked carefully on an individual watch. It should engage securely after installation, release normally when operated, and should not allow excessive movement between the strap or bracelet and the case.
Stainless-Steel and Ceramic Configurations
The supplied information references both 316L stainless-steel and ceramic case configurations.
The stainless-steel version uses brushed finishing across the case to create the more functional appearance normally associated with Pilot’s Watches.
The ceramic version naturally produces a different surface appearance and wrist feel, so the two materials are better considered separate exterior configurations even when the general case dimensions and dial architecture are shared.
Double-Sided Anti-Reflective Sapphire Crystal
The watch is fitted with a domed sapphire crystal with anti-reflective treatment on both sides, according to the supplied specifications.
This is particularly relevant on a Pilot’s Watch because the dial is designed around fast, clear readability.
Anti-reflective treatment helps reduce reflections across the large crystal, making the hands, numerals and dial easier to see from different angles.
The domed profile also contributes to the side appearance of the watch.
Pilot-Inspired Dial Design
The dial continues the recognizable cockpit-instrument style associated with IWC Pilot’s Watches.
Large numerals, strong hour markers and highly visible hands make the display relatively easy to read at a glance.
The release includes three familiar dial colors:
Dial Character
Blue Stronger color with a classic Pilot layout
Green More distinctive color variation
Black Traditional instrument-style appearance
Dial colors can change noticeably depending on lighting, especially blue and green.
For that reason, neutral lighting is more useful when evaluating the actual color than trying to determine whether a photographed dial is an exact color match to another watch.
Asia 7750-Based 69385-Style Movement
The movement is an important point to understand correctly on this version.
According to the supplied specifications, BLS uses an Asia 7750-based automatic movement modified and decorated in the style of the IWC 69385 architecture.
It is therefore more accurate to describe this as:
Asia 7750-Based 69385-Style Automatic Movement
rather than treating it as a native or fully integrated 69385 movement.
Through the transparent caseback, the movement has been visually finished to reproduce elements of the 69385-style appearance.
This distinction between the underlying movement architecture and visible decoration is useful when comparing different versions of the same watch.
Movement Performance Matters More Than Appearance
A decorated movement can improve the appearance through the caseback, but finishing alone does not determine mechanical performance.
For an individual watch, daily rate, amplitude, beat error and beat rate provide more useful information about how the movement is actually running.
The same principle applies when a watch is described as a super clone watch. The term is commonly used in the market, but it is not a defined mechanical specification and does not guarantee the performance of an individual movement.
Actual testing remains more useful than relying on the category name alone.
For real movement measurements and physical dimensions from an individual example, see our BLS Factory IWC Pilot 41mm QC test.
Screw-Down Crown
The supplied configuration also uses a screw-down crown.
Besides checking the external finishing and alignment, the actual crown operation is worth testing.
It should screw and unscrew normally, engage the movement-setting positions correctly and return securely to the case after adjustment.
Crown feel is particularly useful to check on a 7750-based movement because functional operation tells you considerably more than exterior appearance alone.
Strap and Bracelet Versatility
The combination of the 41mm case and quick-change system gives this model quite a different character depending on the strap.
A steel bracelet gives the watch a heavier and more structured appearance, while leather keeps the traditional Pilot’s Watch character.
A rubber strap creates a more casual and practical configuration.
Being able to move between these options without conventional tools is one of the more meaningful functional differences of this BLS release.
Details Worth Checking
When looking at an individual BLS IWC Pilot 41mm, the EasX-CHANGE mechanism is one of the first areas worth testing. Both sides should lock securely, and the bracelet or strap should remain properly seated after installation.
The case can then be checked for its actual diameter and thickness, along with the 20mm strap width.
On the dial, useful points include hand alignment, printing, hour-marker positioning and date/chronograph operation where applicable to the specific configuration.
For the movement, actual daily rate, amplitude, beat error and beat rate provide a clearer picture of its running condition.
The crown, automatic winding and all available movement functions should also be operated before the watch is evaluated as a complete piece.

Frequently Asked Questions
- What size is the BLS Factory IWC Pilot?
This version uses a 41mm case with a 20mm strap width, giving it more compact proportions than the larger 43mm configuration referenced in the supplied information.
- Can the bracelet or strap be changed without tools?
The watch uses an EasX-CHANGE-style quick-release system designed to allow compatible bracelets and straps to be removed and installed by hand.
- Can leather, rubber and steel bracelet options be used?
The supplied release references steel bracelet, leather and rubber strap configurations compatible with the quick-change concept. Compatibility should still be confirmed for the specific strap or bracelet being fitted.
- What movement does the BLS IWC Pilot 41mm use?
It uses an Asia 7750-based automatic movement with 69385-style visual architecture and finishing. It should not be classified as a native integrated 69385 movement.
- What crystal does this version use?
According to the supplied specifications, it uses a domed sapphire crystal with double-sided anti-reflective treatment.
- Is “super clone watch” a movement specification?
No. Super clone watch is a general market term rather than a defined movement standard. The underlying movement architecture, functional operation and actual timegrapher results are more useful when evaluating an individual watch.
