Frequently asked questions
What is the lug width of the Speake-Marin Spirit PIC.20003-64?
The lug width of the Speake-Marin Spirit PIC.20003-64 is 22mm. This measurement corresponds to the internal distance between the two terminal bars (spring bars) of the case. Measuring the lug width accurately with a digital calliper is essential to ensure a perfect fit without play or excessive tension.
Which strap is most suitable for the Speake-Marin Spirit titanium case?
For the Speake-Marin Spirit PIC.20003-64 in titanium, we recommend alligator leather in vegetable tanning (dark brown or burgundy) to maximise aesthetic contrast, or shell cordovan which develops a fascinating patina over time. Premium calf leather (box calf) represents the most versatile choice, while NATO and medical-grade rubber straps are ideal for more sporty daily wear.
How do I change the strap on this watch?
The Speake-Marin Spirit utilises standard 22mm spring bars. To change the strap, you will need a dedicated spring bar tool to compress the springs and extract the terminals from the old strap. Next, insert the terminals into the new strap holes, reposition the spring and ensure the strap adheres evenly on both sides. If you are not experienced, we recommend consulting a professional watchmaker.
Can I use an aftermarket strap compatible with the PIC.20003-64?
Yes, absolutely. Any 22mm strap is compatible with the Speake-Marin Spirit PIC.20003-64, provided it is crafted with construction quality consistent with the instrument (we recommend avoiding low-quality synthetics). Milano Straps offers artisanal leather straps, premium NATO and medical-grade rubber, all tested for reliability and durability over time.
How long does a natural leather strap last on a watch like this?
A quality leather strap (alligator, shell cordovan, premium calf) on a Speake-Marin Spirit lasts an average of 3-5 years in daily wear, depending on frequency of use, climate and maintenance. Vegetable-tanned leather develops a natural patina that improves with time. We recommend avoiding prolonged exposure of the strap to excessive moisture and cleaning it periodically with a soft, slightly damp cloth. Medical-grade rubber straps have greater durability (5-7 years) but less aesthetic versatility.
