 Well Brice...I'm clearly late in congratulating you on the Fortis B-42 Marinemaster arrival!!!!  But...better late than never, so CONGRATS amigo, and welcome to the club!!!!party.gif  I don't know how I missed this post.

As you already know, this Fortis is one of my favorites (heck, I love both the black and lume dial versions).

Thanks for the great writeup!

Don't let the lack of screw-down crown bother you one bit (unless you forget to push the crown insubtlelaugh.gif)...WatchTime published a detailed article several years back with a comparison test of dive watches (Fortis B-42 Marinemaster, Sinn U2, Breitling Superocean Steelfish, Doxa Sub 750T, a Mido dive watch of some kind, and others). The test was done according to the ISO 6425 diver watch standards which requires the watch be submerged in water at 125% of the rated pressure, duration 60 minutes - 25 bar (250 m) in the case of the Fortis. The watch must continue running without noticeable rate change, and no water intrusion is allowed.


The test was hotly discussed, because initially a Breitling SO Steelfish experienced an imploded crystal and a Doxa Sub 750T Pro stopped running so thus, failed the pressure tests (additional tested samples of the Steelfish and Doxa passed).  Now keep in mind that they have a much higher rated initial water resistance, so an ISO 6425 test is going to be much tougher on those two.


The Fortis Marinemaster went through the test without any issues, though the testers first were curious about the push pull crown as well.  The Fortis Marinemaster and the Sinn U2 were the only 2 watches in the test matching ALL criteria of the ISO 6425 standard (including the readability, bezel markings and other criteria) without any failure during the tests.

My favorite combo on this one is the ss bracelet due to the 20mm lug width, but I've only tried it on the ss bracelet and Fortis rubber deployment.  Ian's suggestion above of a notched leather might be very cool...I might have to try that some time.

Enjoy this sweet Fortis icon Brice!!!...thumbsup.gif
