Strap for Speedmaster Professional Moonwatch Alaska Project I

The Omega Speedmaster Moonwatch TI 145.0022 Alaska has a lug width of 20 millimetres. This is the width of the space between the lugs of the titanium case where the strap is inserted. Always verify this dimension before purchasing a replacement strap, using a calliper or measuring it with a ruler between the two lugs.

For the titanium Alaska, pearl grey alligator is the classic choice, emphasizing the glacial tone of the case. If you prefer contrast, black calf amplifies the legibility of the chronograph registers. Brown cognac shell cordovan is ideal if you desire conscious ageing of the strap, as the patina will evolve in synchronisation with the case over time.

The strap is changed using a spring bar tool: insert the small end of the tool into the lateral cavity of the lug and press gently downward to release the internal spring. Remove the spring bar from the lug and install the new strap following the reverse procedure. Ensure that the spring bar is fully seated in the lugs to prevent accidental loss.

Yes, any strap with a 20mm lug width is compatible with the TI 145.0022 Alaska. Always verify that the manufacturer specifies compatibility with 20 millimetres. Straps in alligator, calf, shell cordovan and rubber are all suitable, provided they respect this dimension. On milanostraps.it you will find a complete selection of 20mm straps ready for shipment.

A quality leather strap (alligator, calf, shell cordovan) lasts on average 3-5 years with daily use, depending on the tannage and care. Shell cordovan tends to last longer thanks to the absence of a textile substrate. Vegetable tannage, more delicate, requires regular maintenance but develops authentic patina. To maximise strap life, avoid prolonged water exposure and occasionally apply protective balms specifically designed for watch leather.
