REVIEW: William Jean's Marine Master Type II 22 mm Rubber Strap Part II

Last January, my friend William Jean sent me some new color variants of his Marine Master Type II rubber straps. In addition to the early black and orange models, now they are also available in blue, grey, and red. All is designed for 22 mm lug and accommodates 22 mm SEIKO fat spring bar.

Because my SEIKO 6306-7000 has faded bluish bezel insert, I immediately chose the blue one to wear on the 6306. After wearing it for two months, now I can safely say that this is one of the best rubber strap I ever have.

My previous rubber strap is the SEIKO OEM DAL1BP 22 (a JDM version of the classic flat vent Z22). With thickness around 3.7 mm, William's MM300 Type II is thicker than SEIKO OEM DAL1BP 22 or Z22, but it is softer and more comfortable on the wrist. It curves nicely on my wrist (around 6-1/4 inch) the first time I wear it, without the need for "hot water and cup treatment".

I have tried some silicon straps which are very light and soft but they somehow feel fragile and have unpleasant stickiness on the skin. This MM300 Type II have the best of both worlds: thick solid rubber which gives the feeling of ruggedness and security, but also soft and curves nicely, even on small wrist.

REVIEW: William Jean's Marine Master Type II 22 mm Rubber Strap

My friend William Jean just sent me samples of his new creations: two sets of Marine Master type II 22 mm rubber strap, one set in original black and another set in orange. These are 22 mm version of the original SEIKO SBDX001 MM300 20 mm rubber strap. William went further by making the orange colour version.

Unfortunately, I don't have the original MM300 strap with me anymore for comparison. But, I think the Type II strap has the same feeling like the original one. The inner surface also has the same embossed pattern which prevents the strap from sliding around the wrist. The obvious difference is it does not have the Tsunami wave logo at the end of the strap.

I put the black version on my SEIKO SBBN015 Tuna Can. They make very nice combination. The classic pyramid pattern on the strap (derived from the vintage 6217 and 6105 19 mm "Pyramid" rubber strap) makes it stand out and call for attention. The stiffness of the rubber gives better grip and holds the heavy Tuna better than the original Z22 rubber strap.

Below picture is comparison between William's 6105 Type II "Pyramid" rubber strap on the vintage SEIKO 6105-8119 and the new Marine Master type II on SEIKO SBBN015. You can see where the classic pyramid pattern comes from.

The orange version has very nice shade of orange. It is different from SEIKO's shade of orange. William's orange is more reddish. Below you can see the orange Type II compared to SEIKO 6458-600A orange dial. I think the reddish orange is more suitable for the strap than the SEIKO's orange. It reminds me to emergency tools worn by Search and Rescue personnels.
