◆ CITIZEN PROMASTER Series ◆ Mechanical Diver 200m ◆ Also known as "Challenge Diver" "Fuji-tsubo Diver" ◆ Lightweight titanium material (75g) ◆ Comes with a spare strap (Morellato BYTE, black) I like it because it's lightweight and has a thin case, making it comfortable to wear. However, I have other watches and ended up not using this one, so I'm putting it up for sale. I also purchased a MORELLAT BYTE (worth about 5,000 yen) as a replacement strap, which I will include. (Currently, the replacement strap is attached) 【Condition】 ○ New, unused (only tried on indoors) ○ Purchase date: July 2025 ○ Accessories included (nothing missing from the time of purchase) ○ Comes with a spare strap ○ Spring bar remover included (for removing the original strap) ○ Works perfectly 【Product】 ○ Manufacturer: CITIZEN ○ Series: Promaster ○ Model number: NB6021-17E ○ Color: Black ○ Case size: 41mm diameter, 12.3mm thickness ○ Water resistance: 200m diving waterproof ○ Materials Case: Super Titanium Band: Urethane Crystal: Sapphire glass ○ Movement: Automatic ○ Accessories: Complete (outer box, inner box, warranty, tags) ○ Actual market price: 80,850 yen (List price 115,500 yen) + Strap cost 4,950 yen 【Other】 ○ Please refrain from purchasing if you are sensitive to items that have been handled by another person.
