Even blue tone, balanced numerals and hands, clear crystal and a secure strap attachment let the open dial keep its calm appearance from an angle.
Before dispatch, our QC team reviews blue dial tone, numeral and hand alignment, case proportion, crystal clarity and strap attachment.
IW500710 is the uncomplicated way to add a large blue Portuguese watch to a rotation. The open face has enough room for the numerals and hands to breathe, while the broad case gives the watch a deliberate presence. That makes it useful with relaxed tailoring and smart-casual clothing, especially when a chronograph or calendar would add more information than the outfit needs.
The clean dial needs consistent blue tone from front to side, while the case shape and strap attachment keep the larger format settled on the wrist. The comparison with IW358402 is about scale, making wrist proportion and the intended wearing role the deciding factors.
The 42.3mm width is part of the appeal, so this is not the blue Portuguese to choose when minimum wrist presence is the goal. Its open dial gives that size room to work; the numerals and hands remain easy to locate without a cluster of subdials. In a collection, it fills the space between a plain dress watch and a more complicated Portugieser.
