The Cali Mission Timer is a military inspired divers watch. It features a high readability matte black dial with white printed numerals in C1 Super-LumiNova®. The minute track pays homage to vintage military watches and features 12 triangle hour markers printed with BGW9 Super-LumiNova®. This creates a dynamic and unique dual-compound luminous dial that glows both green and blue.

The flat bezel insert is ceramic to increase strength and durability. The markers on the bezel are in a Mission Timer configuration with a lume pip at 12pm, making it easy to track elapsed time or set a marker for the end of a span of time. This version has a gold paint infil in the bezel insert markers. The bezel itself is a 120 click uni-directional bezel.

The hands are in a Milsub style. These hands were made famous by the Rolex Submariner ref: 5513/5517 which were issued to the British Royal Navy divers in the 1960’s and 70’s. The hands are also filled with C1 Super-LumiNova® to match the lume of the dials numerals.

The case is a solid 39.5mm brushed 316L stainless steel case, with a 120 click uni-directional bezel. It also features a gold plated screw down crown and a screwed-down style case back.

The ‘top hat’ style sapphire crystal has a blue tinted anti-reflective coating (on the underside only) and so provides great performance in every light condition.

Timing is done by the Seiko NH35A automatic movements which run at 21600bph and have 41h power reserve. Like all good military watches this movement features a hacking seconds hand, meaning the second hand stops when the crown is pulled out into setting position. This makes regulation and synchronisation much more accurate.

It comes with a 20mm ribbed style NATO strap with brushed stainless steel hardware.

Secondary strap comes in the form of a black FKM and sailcloth hybrid two-piece strap

Shipping Policy

I aim to ship 'ready to wear' items within 1-2 days of purchase. For custom orders, please allow 3-4 weeks for the watch to be built. I ship from Warwickshire, England so there are no import duties for UK customers.

International customers outside the UK: please note you may be charged import taxes and duties in addition to the purchase price. This is your responsibility to pay these taxes as a buyer.

Return Policy

I don't accept returns, exchanges or cancellations.

But please contact me if you have any problems with your order.

I feel I have described the watches in detail and the pictures are high quality and show the exact product.

Each watch will come with a 6 month movement warranty from the day of purchase. I will therefore only refund an item if there is a fault with the movement or hands within 6 months of purchase date. Please keep your digital email invoice as evidence of purchase and purchase date.

Please note: these are automatic watches and if you stop wearing them they will stop. If this happens give the watch a shake from side to side to get it ticking again. When fully charged it should remain working for up to 41 hours before it stops.

Please note: automatic watches will gain or lose time overnight. An accurate automatic watch has an acceptable loss/gain of up to 20 seconds. Try lying the watch on its side (crown up) to slow it down overnight or on its back (face up) to speed it up overnight.
